Will I be granted residential permit from Bahrain?

I am having 6 months exit/entry visa of KSA.I've been offered job in Bahrain for which they are providng residential permit visa.I am travelling to India then to Bahrain.I want to know whether I'll be stopped at airport of Bahrain becoz I'm having two residential permits one from KSA and other from Bahrain? I want to go back to KSA again, after completion of probation period i.e 3 months and get exit from there.
I just want to keep KSA visa until I get job guarantee.I am Indian and going onto Bahrain as IT consultant.
