I applied the F1 from H1 2 months ago. But international office told me they didn't receive the receipt. Someone said that I can find the receipt # from check I paid. Today, I found it and checked it. It is said it had already approved, but I cannot sure it is the right one because the Application Type is: OS155A, IMMIGRANT VISA AND ALIEN REGISTRATION. Is it the right one? Does one have any idea?
Thanks.
