It is not possible to allow you to travel and return to your country, except after paying the full amount of the loan.
You have to check with the bank to negotiate with him on the way to pay off the loan amount, in order to avoid the bank taking legal procedures against you in addition to banning you from traveling.

You have to negotiate with the creditor
This is to avoid a judgment of imprisonment or a fine, according to the provisions of Article 401 of the UAE Penal Code.
Here is the text of the UAE Penal Code, related to your inquiry:
Article 401
Anyone who badly gave a check that does not have a sufficient fulfillment of an existing and withdrawable or recoverable after giving the check all or some of the compensation so that the remainder does not fulfill the value of the check or the order drawn on him not to exchange it, or who deliberately edited or signed it in a manner that prevents whoever spent it.
He shall be punished with the same punishment from someone who appears to another person or delivers a check to his bearer, knowing that the check has no standing consideration that meets its value, or that it is not withdrawn.
The criminal case shall be terminated if payment or assignment took place after the crime took place and before a final ruling was made on it, and if that happened after the judgment became final, its execution shall cease.
If the court orders that the checkbook be withdrawn from the convict and prevented from being given new books in accordance with the provisions of Article (643) of the Commercial Transactions Law, the Public Prosecution shall inform this order to the Central Bank for circulation to all banks.
If a bank violates the aforementioned order, then a fine of 100,000 AED is required from it.
