I moved to the US in 2001 on an H1-B, received my green card in 2006, moved back to my home country in 2010 and abandoned my green card in 2011. After reading all the different instructions I'm more confused than ever. Do I need to file a 8854? I think not. My home country has a tax treaty with the US and according to the tie-breaker rule I'm considered a resident in my home country so I only need to file 1040NR for 2011, correct? Do I need to file any paperwork in subsequent years or am I done?
Any advice is greatly appreciated
