Nauron,
There is no such thing as a job guarantee, believe me.
I experience this first hand.
GAA already have SO many guys that graduated and are going to graduate from Oxford, tamkeen has already given over ATLEAST 80 Bahrainis a loan to complete training elsewhere (Jordan mainly, some in the UK, some in other places), and if you really know how Bahrain works, you would agree that the GAA guys will NOT be given priority over these other graduates, who are ALL Bahrainis.
GAA helped by giving almost 50 guys interviews with QR, disregarding whether they were GAA's "Oxford" Cadets, or Cadets from other flight schools around the world, and I personally know of 6 graduates from Jordan that are coming to QR and got accepted, and 5 graduates from Oxford, that did not get accepted.
Where is this "Job guarantee"?
Gulf Air has Cadets that joined in May of last year, who have done 14 sectors of flying so far and been doing no flying for the past 2 months, where are they going to find place for the current Oxford guys, the Jordanian guys, and now this whole new batch?
Think about it. If you come back and are guaranteed a job, will the other guys that graduated atleast 2 years before you sit quietly and allow this to happen?
I would personally do my training myself (assuming you can have someone to sponsor you), or take a loan from tamkeen, go somewhere like Stapleford, where training standards are extremely good, prices are reasonable, and you get what you pay for.
Come back, and then do your job hunt.
My two cents.
PM me if you have questions, I am happy to help as much as I can.
