When I was getting my work permits and residency etc..etc... I always had trouble getting through to Belmopan from Caye Caulker, it was about a 50/50 if the phone would just ring or someone would pick up, Mondays were the worse, Fridays too....this was several years ago...also agree you should turn application in , in Belmopan, If your lucky you can get your interview the same day, ask them as they will usually want to give you a appointment, if you have your application complete, you need Belize Police report which takes time. you can get your permit in about a week going through Belmopan, if you are lucky.......
