Can I maintain a residence in the U.S. while establishing residence abroad?

[nebodihome 0]

If I am a U.S. citizen married to a Colombian citizen and we are living in Rwanda, where we will be for over three years and establish residence, can I still somehow maintain enough "ties" to the U.S., such as a bank account and residence, that I am able to then file a CR-1 from abroad (for which domicile in the U.S. is needed?) Perhaps a parallel to this question is will I be able to maintain my resident-of-Rwanda status (for which I can get an income exclusion) while still maintaining a residence and bank account in the U.S. ?

Any information would help, thank you!

You don't necessarily have to prove US domicile for the CR-1, my understanding is that you have to show an intention to restart domicile in the US. It would be useful to have a sponsor on hand, just in case you think you case would need one. I have read here that in most cases the USC goes on ahead to re-establish their US domicile and to get a job/apartment and whatnot. There will be some time apart for sure in this process.

3 years is a long time anyway, lots can change in 3 years.
