The Bahrain Civil Aviation authority like the other civil aviation authorities in the middle east are all JAR based
The airlines also prefer JAR based licenses for someone without any experience
For eg: Qatar airways does not accept FAA CPL holders as second officers or first officers . But they will accept a full FAA ATP license which one obtains upon 1500 hours flying
But Qatar airways will accept someone with 250 hours and passes in all ATPL subjects as a second officer ( some more flying experience required for first officers ) from other aviation authorities . Preference is given to JAA .
They even accept Indian DGCA
So in your case i would strongly suggest getting a JAR license
Some famous schools out there are
Oxford Aviation , FTE Jerez ( trains emirates and qatar cadet pilots ) , CTC wings
The above 3 schools have also been selected by British Airways for their cadet pilot program
I think Gulf Aviation Academy based out of Bahrain has a partnership with oxford aviation
Perhaps you should have a look there
