GAMCA test

Hi I have non segmented vitiligo in my face. When I went for GAMCA test here in India, the guy over there informed me I'm unfit. And he can't take risk of giving me fit certificate  since after reaching Bahrain the medical test will prove I'm unfit.
But vitiligo is not an contagious disease. It's just a skin disorder and it'll not spread to anyone else.

Please advice

I mentioned in another post the issues with Gamca. What you have is not a deportable illness but you won't get a visa if gamca marks you unfit.

Only way around is to come on a visit visa and have your employer convert it after medical in Bahrain. But you cant do that for 6 months (maybe more)  as gamca has already marked you as unfit.
