Hi everyone, I just got my FM3 and I need a little help please. I was told to check in within 30 days. When I turn in my paperwork how long does it take to get it back? I knew I had to check in but I didn't know it would take several days for the paperwork to be done. I thought they just stamped it and that was that. Now I found out I have to leave it . The problem is I am only going to be there for 15 days. Do you think that will be enough time to get the papers back? Also when I leave do I have to do anything different at the airport? When I got my FM3 in the states they were not very clear as to what I needed to do when arriving and leaving Mexico. I was given the form to fill out for when I arrive this time ( by plane ) but in the future which form am I suppose to use? I was told to stand in the MX line at the airport. Is that what I should do? All help will gratefully appreciated. Thank you all in advance for any information!!!!!!!
