American immigrants should have a physical examination a few days in advance.

If you receive an interview notice, you should receive a physical examination form and other forms in the envelope to inform you of the physical examination and when to see the consul. This period of time is usually about 2-3 weeks, so you should be prepared before, such as all notarial certificates. After receiving the notice, you should go to the physical examination immediately, fill in the form and verify whether the information of the economic guarantor is up to date. If you pass the interview, you can get your passport and a big envelope back in the afternoon, and then you can buy a plane ticket and prepare to leave.
