@Phil_K_IR1 Thanks. The email I received on 4/19 was a reply to my email sent to them on 4/4 and my case also updated on 4/19. My petitioner did not receive anything though.
After complete silence in March, I saw 5 updates on my case since April (4/4, 4/9, 4/6, 4/18 and today 4/19). Also I received the 1st personized email message today. Does this mean they are really working on my case?
I file my tax return with IRS every year b/c I work in USA now, but I have a SSN obtained many years ago when I was a student under F1. If you do not have income from US sources, I do not see the need to file tax return with IRS, but please consult your laywer to be sure.
I think the mecical exam is good for 6 months and the police report is good for 2 years. After you receive your IV visa, if you activate it within the specified time frame, you should not need to to them again.
