The F2A visa is a category of US family-sponsored immigration visa for spouses or children of US Green Card holders. US Green Card holders may file Form I-130 with the US Citizenship and Immigration Services (USCIS) to sponsor their foreign spouses and unmarried children under the age of 21 for an F2A immigration visa.
Required Documents:
Form I-130, Form G-325A, notarized birth certificate and marriage certificate of the applicant (one original and two copies), photocopy of both sides of the sponsor's Green Card, two white-background photos of the applicant and the sponsor, photographs of the couple or the parent and child, a $355 check for fees, etc.
Important Points for the Interview:
Be prepared to provide proof of relationship, have an understanding of how your parents arrived in the United States, their current occupation, how they met, when they were married, and all background information regarding your parents, especially their tax filing status. You should also be prepared to answer why you are going to the United States and what you intend to do upon arrival.
Special Note: Only answer what is asked. Do not volunteer extra information, as saying too much may lead to mistakes. Please prepare a collection of photos of you together from different periods, as well as family photos.
