The United States Immigration Service sends a letter to the place of residence.

When your appointment time is up, the Immigration Bureau will inform your applicant that he wants to provide a lot of information about him.

Only the materials provided by him are complete and sent to the immigration office.

Your suitcase can only reach Guangzhou.

Then it will take three to four months to do your background check.

Guangzhou will send you a letter after it is passed.

The speed depends entirely on the speed at which your American applicant submits the materials.

Contact your American applicant.

You have been normal for four months.
