FAA course - distance learning
There are options to 6 weeks stay in US to gain FAA dispatcher licence - 6 days!
I looked at the showhorses and decided on a workhorse - AGS (google agschools).
They have trained many foreign students and have an understanding of the dispatching profession outside the US. Their distance learning option (DLC) meant dedicated work to prepare for the FAA written tests at home and then 6 very full but ultimately worthwhile days in the US to cover the practical material and take the oral.
I do suggest to go a few days in advance to take the FAA written test and recover from jetlag as the 6 days does need all your attention. ~10 days including days of arrival & departure should do it depending on your travel schedule and the FAA test centre hours.
No links with AGS other than as a very satisfied & paying customer.
