Travel status of an employee after leaving work without cancellation

Hi

I have been working with Emirates Airlines for almost 9 years, and due to some emergency reason, I left Dubai going back home.

After that, I sent my resignation by email. My employer said that they need my passport to cancel my residence visa otherwise I will be blacklisted by the UAE immigration.

This case has been almost seven months ago. If I decided to come back to Dubai, how to issue tourist visa with no issue or being refused?

Do I have to pay a penalty?

How to remove the ban or blacklist?

Will they arrest me at the airport?

Warm regards,

Tony
