Dual Residency Question

Dear Fellow Expats,

Does anybody out there have any experience with being a citizen of one country (let's say Canada) and allowed to have U.S residency (green card) and Ecuadorian residency concurrently-that is to say maintaining both U.S. residency and Ecuadorian residency at the same time without having to give up one for the other?

Your comments welcome. Thanks.

You can have multiple residencies.

I'm an Ecuadorian with dual citizenship, both U.S. and Ecuador. No problem there.
