Consequences of a civil case by the bank for a credit card

Dear Sir,

I am living in the UAE.

Last February 2019, a bank filed a criminal case against me for credit card and security cheque bounce of AED 60000. I paid the fine and got released from the public prosecution at al Rahba, Abu Dhabi.

Afterwards, one law firm contacted me chasing for the unpaid dues from that bank and said they will file a case against me. I am jobless and searching for a job for the last 4 months due to my termination.

If they file a civil case, will there be any impact on applying for a new visa? It is possible to overrule any court decision? How can I get released from this situation?

Hence, I don't have any single dirham with me to pay the bank. Also, advise if the police can arrest me on the basis of this civil case immediately.

Your favourable response will be highly appreciated.
