hi everyone

came into the country on a k3 visa 3yrs ago,but problems with previous marriage made it impossible to adjust my status and i had to move on(long story)

met another woman while still in states and got married,refiled I130 with new wife and at 1st interview it was denied cos of previous I130 but we appealed and more evidence was sent then they approved the I130 actually the immigrations officer called to tell me that he just could not bring himself to deny the application moreso with all the documents we submitted.

then 3 days later I get an approval notice in mail.with my status changed to IR6 but 2 days after that I get another letter asking me to come to the immigrations court titled notice of hearing in removal proceedings but it was all based on me being out of status(reasons given) not on the previous marriage(i.e was not accused of marital fraud)

went to see a lawyer and he said I should also file I129F for the judge might ask me to leave and since the I130 has been approved the I129F will make it faster for me to get back into the country(according to the lawyer)

I was thinking,is the I129F not filed to speed up the I130 and if my I130 has been approved why do I have to file I129F

also,since my status has been changed to IR6 and I got the approval letter,what happens next?

Thanks for all responses
