From what I read, the U.S. Immigration policy is very complex. The U.S. allows for an annual worldwide limit of 675,000 permanent immigrants, with certain exceptions for close family members. Congress and the president determine a number separate from the number allotted to immigrants for refugee admissions. Immigration acceptance is determined on: the reunification of families, admitting immigrants with abilities that hold value to the U.S. economy, protecting refugees, and promoting diversity.
Bringing families together is an important issue to consider when planning an immigration policy. The family-based immigration category allows U.S. citizens and lawful permanent residents (LPRs) to bring certain family members to the United States. The U.S. allows for 480,000 visas to be available for the family-based category per year. These immigrants are admitted to the U.S. either as immediate relatives of U.S. citizens or through the family preference system. Petitioners need to be at lease 21 years of age to petition for their parent’s to receive visas and all petitioners must meet certain financial requirements in order to be considered. Spouses and unmarried children who are under the age of 21 years also fall under immediate family. There is not a limit on visas available for immediate relatives.
There are a limited number of visas per year for the family preference system. The preference system includes adult children married or unmarried, brothers and sisters of a U.S. citizen. The petitioner must be at least 21 in order to petition for his/her sibling. Spouses and unmarried minor/adult children of LPRs also fall under this system. Congress has made a complicated system for calculating the available number for yearly family preference visas. This number is determined by subtracting the number of immediate relative visas issued the previous year as well as the number of aliens that were paroled into the U.S. the previous year from 480,000. Also any unused employment preference immigrant visas from the previous year are then added to this number. The law says that family-based visas allocated through the preference system cannot be lower than 226,000. Consequently, this makes for the total number of family-based visas to exceed 480,000.
The Employment-Based immigration is the second category that is allocated to immigrants. Immigrants given this visa are given because they have valuable skills that the U.S. can use. These visas can be temporary or permanent. There are over 20 different types of visas for temporary nonimmigrant workers. Such types include athletes and entertainers as well as religious workers. Many highly skilled or immigrants with temporary work visas are sponsored by the company that they are working for. Permanent employment-based immigration is set to a rate of 140,000 visas per year and this is divided into 5 preferences where each has a limit.
The INA also places limits on the allowed number of immigrants to come from once country into the States. No group of permanent immigrants (family-based and employment-based) from a single country can exceed 7% of the total amount of people that immigrate to the U.S. in one year. This is a limit set to prevent any one-immigrant group from dominating immigration patterns to the United States.
The U.S. offers several categories of legal admission for people who are fleeing their country due to persecution or who are unable to return due to life-threatening conditions. Refugees are admitted to the U.S. based upon inability to return home because of a fear or persecution due to their race, social group, religion, national origion or political opinion. Refugees are to apply for admission from outside the U.S. Each year the president and congress determine a number for refugee admission.
Immigrants that are already in the U.S. that have been persecuted or have a fear of persecution upon their return may apply for asylum within the United States or during entry while seeking admission. They must petition within one year of arriving in the U.S. There is no limit on the number of individuals who may be granted asylum in a given year nor are there specific categories for determining who may seek asylum. Refugees and Asylees are eligible to become LPRs one year after admission to the United States as a refugee or one year after receiving asylum.
The Immigration Act of 1990 as a dedicated channel created the Diversity Visa lottery for immigrants from countries with low rates of immigration to the United States. Ever year around 55,000 visas are assigned randomly to nationals from countries that have sent less than 50,000 immigrants to the United States in the previous 5 years. To be qualified for a diversity visa the immigrant must have a high-school education (or its equivalent) or have, within the past five years, a minimum of two years working in a profession requiring at least two years of training or experience. This program especially benefits Africans and Eastern Europeans.
To qualify for U.S. citizenship through naturalization, an individual must have had LPR status aka a green card for at least 5 years. There are other exceptions such for people who served in the military. Applicants for U.S. citizenship must be 18 years or older, they must demonstrate continuous residency, and display “good moral character,” as well as pass the English and U.S. history/civics exams. The person/s also need to pay an application fee, and complete other requirements.
