When people move from their home country to the United States, their families are not always able to stay together. However, once immigrants earn citizenship or lawful permanent resident status, they may sponsor relatives in obtaining family immigrant visas. The requirements for these visas are governed by U.S. immigration laws and are enforced in every state, including California.
In order to apply for an immediate relative or family preference immigrant visa, the sponsor must primarily reside in the United States. Sponsors must be at least 18 years old to sign the forms required for family immigrant visas, but there is no age requirement to petition for immigrant visas for family members. If their relatives are parents or siblings, however, the sponsors need to be at least 21 to file a petition.
