The USCIS uses the Alien Registration Number – ARN to identify U.S. permanent residents.
When a citizen of a foreign country enters the U.S. to immigrate permanently, he or she is issued the Alien Registration Number. This is also called a USCIS number.
The number is unique to each person. It is either a seven-, eight- or nine-digit number. If a person was issued a Green Card after May 10, 2010, the numbers can be found on the front and the back of the card.
The Green Card is also known as an immigrant visa. The Alien Registration Number is not issued to citizens of foreign countries who are entering the U.S. with a nonimmigrant visa. Nonimmigrant visas are visas for a temporary stay in the U.S.
The red number printed on the nonimmigrant visa inside the passport is the nonimmigrant number.
What is a Green Card?
A Green Card is an official document issued to citizens of a foreign country who are authorized to become permanent residents of the U.S. It looks just like an identification card.
The Green Card shows the applicant’s name, country of birth, date of birth, sex, expiration date, permanent residency date, and the alien registration number (USCIS #).
The two most common ways of becoming a permanent resident of the U.S. are through a family-based petition or through an employment-based petition.
What is a nonimmigrant visa?
A nonimmigrant visa is an official document that is printed on the passport of a citizen of a foreign country. The nonimmigrant visa is issued for a specific period, which means that a nonimmigrant visa holder can only stay in the U.S. for the time permitted.
Nonimmigrant visas are available for various reasons. Some examples are the business visa, the tourist visa, and the student visa.
The nonimmigrant visa shows the applicant’s name, country where issued, date of birth, nationality, sex, expiration date, visa type and type of entries, issue date, and the nonimmigrant number.
