Hello, what is the process to change from F2B to F1? Im in the all areas category and just need movement of 7 months to get to Apr 2018 if i switch to F1. As someone mentioned, the F2B can move faster than F1 sometimes, so i've held back since nothing has really moved in the last 1-2 years.

Do you just send a signed letter stating you want to change F2B to F1 + copy of citizenship + copy of I-130 approval letter to the nvc address?
