Hi Rizmin, All the guys here have given the true fact. i guess you didnt understood. See the fact is, in order to work in Dubai, you need RP Visa there and they cannot out your RP visa unless your Qatar RP Visa is cancelled. Now in order to cancel Qatar RP Visa, you have to clear all the dues and loans. Now your guarantor will have to transfer your loan under his name and he will start paying the dues. after this finally your visa gets cancelled.

I hope i might have outdated info. someone have updated info, do comment.
