Hi. I am married to an American citizen and achieved my green card in mid- 2007 so he could work in Tennessee for a couple of years. We returned to Australia permanently in December, 2009. I took my 18 year old back there to visit with our good friends in late March, and I was taken aside by officers who advised me to either get a reentry visa quick smart or abandon my green card back home. We are not thinking of working in the States in the next 10 years, so I found some reference to an I - 407 form and downloaded it.
I was told by the officer at LAX I would have to hand in the card in person in another capital city- is this true or can I send it and the card by mail? If I do take the plane trip for the consulate do I need the I - 407 in hand? I tried getting an appointment like the airport officer said this evening and it redirected me- I cannot seem to keep on the Infopass site, which is frustrating.
Thanks for your help.
