My husband and I went to USCIS Application Support Center this morning. He sent all the necessary documents in applying for a green card. If you came here to America under K1 Fiance(e) Visa, this may help you.
Here are the few things that might help you:
1. Authenticated Birth Certificate.
You can get this at National Statistics Office. Click here to know more
2. Medical statement or medical summary from S.L.M.C.E. For reference.
3. G-325A Biographic form. Your new information after you get married will be
listed here. You can download the form with the same site where you downloaded
it when you were applying for your K1 visa, the one you sent to your petitioner
that is in the US.
4. Income Tax Statement of Statement of Support. This is from your petitioner
that you married with.
5. 2 copies of passport size picture. It should be taken in less than a month.
6. A copy of your marriage certificate.
7. Payments for the green card processing.
After completion of all the requirements, you and your husband or wife which was your petitioner can mail all the documents together with the check as payment in the state where your husband or the person you married to is residing.
In less than a week, we received a notice telling me what to bring and to check if they got all my information correct. In less than a week, I got the confirmation date for my biometrics appointment.
When you receive the first letter of notification from USCIS, they will tell you what are the other things that you have to do. If you completed all these steps, you are on your way for your green card. You will be notified if your application is granted.
Good luck!
