How to check if there is a ban or restriction to enter the UAE?

Hello,

I overstayed on a Sharjah visit visa and I applied for a fine reduction. My application got approved and I paid the fine and get updating paper from Sharjah immigration.

After a few days, my fine is cleared from the system and I booked a ticket to go back to my country from Dubai, but Dubai immigration canceled my boarding pass and asked me to go back to Sharjah immigration and get outpass if I want to leave.

I applied for outpass and traveled from Sharjah airport. Again, immigration stopped me and said that I am not cleared and that if I want to leave, I can not come again. I explained well and they stamped exit on my passport and asked me to go.

Now, I am scared that I got banned or blacklisted. How can I check if I have a ban or restriction to enter the country again?
