first check how many months payment is delay and then which bank is that if you have local bank like (Emirates Bank, Dubai Islamic Bank, NBD Bank etc) then for sure after 3 months delay payment you will get travel ban.

Once you will go to Airport same time they will take you to immigration jail Al Aweer you will be having a court next day, and after 15 days will be your sentence remember the pending payment is one hunderd or one hunderd thousand the punishment will be only 40 days only.

and if its international bank like RBS, HSBC, Barclays then its not too strickt you can convence them but once its travel ban even bank can not remove till you will not pay.

Go to online service of the bank send them mail comunicate with them they will give you solution even you are any where in the bank you can pay them.

Best of luck..............!
