What problems do American consulates in Guangzhou usually mention when they are "brothers and sisters American immigrants"? What materials need to be prepared in advance?

1. Visa photos (4 photos, including physical examination, should be enough)

2. Notarization (notarization of birth, notarization of punishment): Even if you handed it in before, you should bring it with you to prevent the beautiful collar from being lost.

3. The applicant's tax bill for the last three years, W2, employer's letter (if any): I may have submitted it long ago, but I also brought it for the same reason.

4. The more photos of respondents and applicants, the better, preferably at different times and on different occasions.

Family immigrants and marriage immigrants are different, mainly depending on whether the economic security is sufficient. White-collar workers in America usually ask questions about family relations.
