Deportation and possibility to return back to the UAE

Hi,

I am an Indian and living in Dubai for the last 25 years. My son had a criminal case on document forgery and he served three months jail term then got deported from the UAE.

I am not very sure if he has been blacklisted and got a lifetime ban. The judgement states "3 months jail and deportation". Recently I checked at Sharjah Immigration and found no ban on him.

However, I'm a bit scared that he will be blocked and arrested at the airport on arrival on a tourist visa.

Could you please advise how to check with the Airport Immigration and to ensure that he has no ban and can enter the country?

Kindly revert.
