Do not be dumb
You can do the full FAA Dispatcher course by Jeppesen in Singapore at Mil-Com for US$5,000 or in Dubai at Emirates for US$6,500. Now you would have to latter travel to the U.S. to take the FAA ceritifcation exams which consist of the comuterized wirtten, oral and practical exams. While the Jeppesen certificate is good for 90 days to do all this, if you work as a dispatcher anywhere, Jeppesen reissues the graduation certificate even years latter free of charge to allow you to go the states and tkae the FAA exams.
Advantages:
In Singapore your FAA course is also appoved by the CAAS and everybody has gotten jobs, even foreigners who come and take the course to get a job in Singapore before they complete the full 6 weeks course. Jennifer at Mil-Com goes out of her way to assist foreign students.
In UAE your FAA course allows you to take an oral and practical exam and be issued a UAE license which expires every 2 years but can be renewed with a 3 day refresher course. It takes a bit longer in UAE, perahps 2-3 months, but their graduates get jobs too.
The idea is to have a job at the end... an FAA certificate without a job is so useless!
Good luck....
