<human>: My husband and I are like brother and sister at this point.

Stopped having intimacy before we actually tied the knot (married 4 of the 6 years of our relationship). Actually it was only for the first year of our "dating" or courtship that we had an active sex life. 2nd year of dating, I think it happened just once. Honestly I regret saying yes to his proposal but I said no to a previous proposal (from someone else) and I grew to regret it so much, I felt some kind of inner pressure not to lose the precious opportunity to get married should it come around again....

Anyway, at this point, we are basically living apart, have both had affairs, and have calmly and supportively discussed our mutual wish for a divorce. The problem is, his green card application is still being processed. Long story but it's been a long process with lots of delays.

My question is...for people who know how the green card app process works (in the USA)-- how careful do we have to be about potentially being seen with or creating evidence of being with other people?  Our relationship was never fraudulent, there is ample evidence of a genuine random meeting, initial period of being in love, meeting families, honeymoon, millions and gillions of tender emails etc.....  But at this point-- we no longer wish to be a couple. But I want to help him finish his process of migrating to the USA because he will be so much happier here.

We both feel torn. On the one hand, no sex for over 4 years and we both can't see a way back to that. We really do feel like brother and sister, and even more so, we don't really enjoy passing the days together anymore. We would both be happier if we were free to date but ARE WE FREE TO DATE?

Can you provide a brief overview of the text?
<bot>: Husband and I want to divorce but don't want to jeapordize his visa / green card app for my home country. How careful should we be in terms of obviously moving on and being with other people?
