I have a personal loan and credit balance in UAE. Until now, I have paid my installments without delay. Mean time I've got an good offer from Qatar and hope to join them. I know one solution is produce a guarantor. Some say this might give me difficulties.They say- Without informing bank, I can leave and but keep paying without any delay. But I have a doubt when I make exit here, whether bank can stop me at airport. Please advise me.
