Issuing work permit in bahrain

hi guys,

hope someone can help me on my inquiry..im currently employed here in bahrain for almost 4yrs..my visa was expired last yr july and until now my employer didn't renewed it...i keep asking him but he's keep telling that it's on process..then i found out from the lmra coz i inquire them thru online that my visa was terminated last yr october..and i follow up my employer in my visa because im planning to go for a vacation this coming november and he told me that it was already on process and he paid 400bd for my new visa..but sometimes i don't want to trust him because its been a year that he's telling me that its on process. I believe at first that I cannot go for a vacation in my home country if I don't have visa here that's why I keep following him up but then I heard from someone if I'm already overstaying here in bahrain the lmra will really not issue a work permit for me and I have to exit first this country bahrain so they can issue for me a visa and there's a payment will be given in the immagration?Can someone clarify me on my situation and on what should I do and if ever who should pay the imigration for my overstaying is it my employer or me?thank u
