Family unity is very important for the United States, thus, U.S. Citizens are allowed to petition for some qualified relatives to come and live permanently in this country with them. These eligible immediate relatives have special priority which includes an unlimited number of visas available for them.

According to the Immigration Law of the United States, an immediate relative of a U.S. Citizen could be any of the following:

1. Spouse
2. Unmarried child under the age of 21
3. Parents of a U.S. Citizen over the age of 21.

​For your reference, not only U.S. Citizens are allowed to petition for their immediate family, under the immigration laws exist four (4) preference categories through which a family member might immigrate permanently and these categories are based on the relationship between individual commonly called “beneficiary” and his or her “petitioner” who can be either a U.S. Citizen or a Lawful Permanent Resident.​
