We are working on getting resident visas. There’s a program that if you (1) are in Mexico on an expired visa, (2) visited Mexico at least once before 2020, (3) have money to pay fines for expired visas and fees for the “regularization” program, (4) have more money to prepay four years of temporary residency visas, and (5) find a lawyer who can walk you through the Mexican immigration process, then all good! We hope.
Next step: wait a few days to come back for fingerprints and photos. Next next step…?
