If you are from the Central American region you might want to try La Costena, TACA's Regional Airline in Nicaragua.
They fly out of Managua, Nicaragua (MNMG) to San Jose, Costa Rica (MROC) as a DHL cargo feeder. And they also fly passengers and charter flights domestically.
The residence documents are not a problem. We used to have FO's from Spain, Mexico, Costa Rica and the US.
Give them a call. I think they need pilots.
