I see, but what if I have to stay more than 2 yrs? I did read about the I-131 from the USCIS website http://www.uscis.gov/green-card/afte...anent-resident and I also read about applying for an SB-1 visa http://travel.state.gov/content/visa...sidents.html#2
but as they mention "Are returning to the United States from a temporary visit abroad and, if the stay abroad was protracted, this was caused by reasons beyond your control and for which you were not responsible." which will not be true in my case since if I am not returning early it's because I am working at a university in Europe.

Ah! thanks.

Also I don't know why the admin modified my post heading, since it is a little misleading, as I am questioning whether I should apply for green card itself.

A K-3 visa seems to work in my case, but since the wedding was in the US, I guess I will have to go to my country of residence (my home country?) and apply for a K-3 http://www.workpermit.com/us/family_visas/spouse.htm
