Legal Question in Immigration Law in New York

I believe I tried to answer your question earlier but perhaps was not clear. You should submit all of your documents together (including tax returns) with your application if you want your case to be processed quickly. Any documents that you wait and submit at an interview will only delay the processing of your case. I also wanted to make sure that you understand that if you had a 2 year return requirement attached to your J-1, converting to an F-1 will not make that requirement go away. You would need a waiver if you were subject to that requirement.

It is always better to submit everything from the beginning. Make sure you are not subject to Two-year Home-country Physical Presence Requirement Conditions as a part J visa. As to tax returns, depends on when did you get married, of course, concentration is on petitioner's financial ability.
