The United States' immigration system is a complex network of visas, humanitarian relief, pathways to permanent residency, and citizenship. The country's immigration laws and rules have evolved over time, with a focus on border control, enforcement of laws on hiring immigrants, and eligibility restrictions. While there have been efforts to create immigration laws, the dynamic nature of political, social, and geopolitical factors influences the outcome. For instance, the Trump administration's crackdown on immigration resulted in increased arrests and deportations, while President Obama's executive actions in 2012 and 2014 aimed to provide relief for young adults brought to the country illegally. The ongoing changes and varying approaches to immigration by different administrations highlight the challenges in establishing comprehensive and consistent immigration laws.

What You'll Learn

Political, social and geopolitical factors
The passing of the Immigration and Nationality Act in 1965 was influenced by a combination of political, social, and geopolitical factors. This Act created a new system that prioritized family reunification and skilled immigrants over country quotas.
Political factors have always played a significant role in shaping immigration laws. For instance, the 1790 law restricted citizenship to free whites of "good moral character" who had lived in the US for at least two years, reflecting the political climate of that era. In 1870, the right of citizenship was extended to those of African origin, marking a shift in political ideology.
Social factors, such as public opinion and demographic changes, also influence immigration laws. For example, the 1921 and 1924 laws aimed to restore earlier immigration patterns by imposing numerical quotas favoring northern and western European countries due to the increasing immigration from southern and eastern Europe.
Geopolitical factors, including international relations and global events, have also shaped immigration policies. The 1952 legislation, which allowed a limited number of visas for Asians, was a step towards dismantling the race-based exclusionary policies. Additionally, the 1965 Immigration and Nationality Act ended the national-origins quota system, leading to a shift in immigration demographics with a higher proportion of immigrants from Asia and Latin America.
Furthermore, concerns about terrorism and unauthorized immigration have led to subsequent laws in 1996, 2002, and 2006 that tightened border controls and admissions eligibility. On the other hand, humanitarian considerations have also influenced policy changes, such as the 1990 law that provided "temporary protective status" to shield immigrants from deportation to countries facing crises.
In conclusion, the interplay of political, social, and geopolitical factors has significantly shaped the evolution of immigration laws in the United States, reflecting changing societal values, global events, and the complex dynamics of international relations.

Humanitarian relief
The United States has long been a haven for people worldwide seeking protection and refuge. The U.S. immigration system is a complex network of visas, humanitarian relief, pathways to permanent residency, and citizenship. Humanitarian relief is a critical aspect of the U.S. immigration system, offering temporary protection to individuals facing crises or emergencies in their home countries.
One form of humanitarian relief is Temporary Protected Status (TPS), which provides temporary legal status to eligible nationals of designated countries who are present in the United States. TPS allows individuals to remain in the U.S. temporarily without fear of deportation and is granted when returning to the home country is deemed unsafe due to ongoing armed conflict, environmental disasters, or other extraordinary conditions.
Another form of humanitarian relief is Deferred Enforced Departure (DED), which is an administrative stay of removal granted by the President. DED prevents certain individuals from being deported from the United States for a specified period, typically when their home country is experiencing instability or crisis. DED does not lead to permanent residency or confer any long-term immigration status.
Humanitarian Parole is another option for individuals seeking temporary entry into the United States. This form of relief is typically used in emergency situations when an individual cannot obtain a visa. Applicants for Humanitarian Parole can apply to U.S. Citizenship and Immigration Services (USCIS) or Customs and Border Protection if they are at a point of entry. Parolees who are authorized to work may seek employment opportunities.
Additionally, asylum is a form of humanitarian relief granted to non-citizens who fear returning to their home country due to the risk of persecution, torture, or other inhumane treatment. Asylum seekers must navigate a complex process involving multiple government agencies, and they are protected under the Convention Against Torture (CAT), an international treaty incorporated into U.S. immigration law.
The U.S. immigration system aims to balance humanitarian relief with other considerations, such as national security and economic interests. While humanitarian relief provides vital protection to vulnerable individuals, it is just one component of the broader immigration framework, which also includes family reunification, employment-based visas, and other pathways to legal status.

Visa categories
The US immigration system is a complex network of visas, humanitarian relief, pathways to permanent residency and citizenship, and temporary status for people facing crises in their home countries.
The US offers a variety of non-immigrant visas for temporary stays, including:
- Tourist visas
- Student visas
- Temporary worker visas
- Religious worker visas
- Medical treatment visas
- Visas for travel as a crew member on a ship or aircraft
- Visas for representatives of foreign governments or designated international organisations
There are also immigrant visas, which allow the holder to live and work in the US indefinitely and receive a Green Card. Immigrant visas include:
- Employment-based preference visas, which are subject to annual caps and numerical limits on how many immigrants can come from one country.
- Family-based immigration visas, which allow US citizens and lawful permanent residents (LPRs) to enable certain family members to gain LPR status.
- K non-immigrant visas for the fiancé(e)s and spouses of US citizens.
- Diversity visas, which are part of an annual lottery that randomly selects applicants from countries with low immigration rates to the US.
In addition, there are humanitarian relief options, such as the Deferred Enforced Departure (DED) and Deferred Action for Childhood Arrivals (DACA) programs, which provide temporary protection and work authorisation for individuals who meet specific criteria.

Deportation
The U.S. may deport non-citizens for several reasons, including entering the country without proper authorisation, violating the terms of their visa, or overstaying beyond the authorised period. Additionally, non-citizens who commit crimes or pose a threat to public safety may also be subject to deportation. In some cases, expedited removal may be enacted, bypassing the need for the individual to attend a hearing in immigration court.
The Trump administration's revival of an 85-year-old immigration law, the Alien Registration Act, has put undocumented immigrants in a difficult position. This law requires virtually all non-citizens in the country to register and submit fingerprints to the government. Failure to comply can result in charges and potential deportation. Critics argue that this places undocumented immigrants in a catch-22 situation, as registering provides incriminating information, while refusing to register is also a punishable offence.
To protect themselves, individuals facing potential deportation are advised to carry evidence of lawful entry or current lawful status in the U.S. They should also be aware of their right to remain silent and request to speak to a lawyer. In cases where individuals fear returning to their country of origin, it is crucial to state this fear clearly and seek asylum.
While the U.S. immigration system offers various pathways for visas, humanitarian relief, and permanent residency, the complexity of the system poses challenges for immigrants navigating it. The involvement of legal professionals can increase the chances of success for immigrants, but access to legal services may be limited.

Pathways to citizenship
The United States immigration system is a complex network of visas, humanitarian relief, pathways to permanent residency, and citizenship. The US has several pathways to citizenship for undocumented immigrants.
One pathway to citizenship is through the American Dream and Promise Act, which was passed by the House of Representatives in March 2021. This bill offers a pathway to citizenship for Dreamers, individuals holding or eligible for TPS, and undocumented farmworkers and their families. The Dream Act of 2021 is currently with the Senate, which joins a similar bipartisan Dreamer legalization bill.
Another pathway to citizenship is through the Farm Workforce Modernization Act, which was also passed by the House of Representatives. This bill offers a pathway to citizenship for undocumented farmworkers and their families, which could provide legal status to nearly 1 million undocumented immigrants.
The Citizenship for Essential Workers Act is another piece of legislation that provides a pathway to citizenship for undocumented essential workers, who have played a crucial role during the COVID-19 pandemic.
In addition to these legislative pathways, there are also other avenues to citizenship. One example is family-based adjustment of status, which allows individuals to transition from a non-immigrant visa to permanent residency with the help of a family member or immediate relative. Temporary Protected Status (TPS) is another pathway that allows individuals to legally remain in the US while their home country recovers from a crisis. Deferred Action for Childhood Arrivals (DACA) is a program that permits certain individuals who entered the US as children to remain and work lawfully, although it does not confer a path to permanent legal status and requires renewal every two years.
To apply for US citizenship, individuals must be 18 years of age or older, have permanent residence in the US for at least five years (or three years if married to a US citizen), and be physically present in the country for at least half of that time. They must also be able to read, write, and speak basic English, although there are exceptions for certain individuals. It is important to note that applying for citizenship allows USCIS to reopen the entire immigration file, which may lead to declined applications or removal proceedings in some cases.

Frequently asked questions
Immigration laws are complex and constantly evolving. They are influenced by various factors, including historical patterns, economic needs, humanitarian considerations, and political agendas.
One challenge is balancing economic needs with social concerns. For example, admitting skilled immigrants who can contribute to the economy while addressing public worries about job competition or cultural changes. Another challenge is ensuring fairness and efficiency in processing immigration cases, as the system can be complex and legal representation may be costly.
Immigration laws in the United States have undergone significant changes. Initially, laws favored immigration from certain European countries and restricted immigration based on race and nationality. The Immigration and Nationality Act of 1965 shifted the focus to family reunification and skilled immigrants. Subsequent laws addressed concerns about terrorism and unauthorized immigration, emphasizing border control and enforcement. More recently, there have been efforts to provide relief for specific groups, such as the Deferred Action for Childhood Arrivals (DACA) program.
