Buddy, if it's possible for you to get a temporary job in UK while waiting for this one, please do.
The new Seychelles government is really frustrating companies efforts to bring expatriates. Even during their election campaign, it was one of the promises they made to Seychellois (locals) that if they win, that expats won't be in Seychelles again. Now they won, they are doing everything possible to fulfill that promise, even when they know that businesses in Seychelles can never survive without expatriates.
So don't fold your hands and be waiting, because you don't know what the outcome will be.
All the best!
