Received a short message from an American immigrant visa letter.

It depends on whether your stepmother is suitable for you or your father is suitable for you. Stepmother's application for scheduling is about 1 year, and your father's application for scheduling is about 3 years.

Generally, 2-6 months after completing the materials, if there is no problem with the application, you can receive an interview letter. You don't have to worry, as long as it doesn't exceed 2 1 year, it's fine.
