Japanam,
If you're looking at moving out here as an instructor with the aim of moving to another company on charter in the area then I have heard of this having worked before.
However, please do bear in mind that in order to change sponsor (employer) you will need a letter of no objection (NOC) from your first sponsor. If, for whatever reason (maybe they don't want you to leave them), your flight school doesn't want you to go and refuse to give you the NOC then you will not be able to work for any other company in the whole GCC for a couple of years (starting AFTER the completion of your contract).
Whatever you decide, I wish you all the best with it.
Chinchilla.
