Hi there, I am a US spouse and my husband lived with me in the US on a Green Card for 6 years before we left recently to live in his country. We are wondering what to do now with respect to the Green Card. In practice, rather than in law! 
If my husband officially gives up his Green Card, will it be easy for him as a former resident and spouse of a US citizen to get a tourist visa to the US? Or will it be back to square one - proving income and assets, and roots in his home country? Also, how would the continuing marriage and former Green Card affect his chances of getting another GC in the future, should we decide to move back?
If he doesn't give up the Green Card, what, in practice, needs to happen for him to retain it (ie. frequency of visits, duration, etc.) So far, they haven't said anything, but I wonder if it is just a matter of time...
Thanks for any advice!
