First port entry will affects other city residency?

Hi everyone,

If I enter in Dubai from other country and I want to get a residency from Abu Dhabi, Will I have a problem? or Do I have to get a residency from Dubai?

No

You can enter from any place ...

You mean enter from another Emirate (not country, because all 7 Emirates come under one country United Arab Emirates)?  UAE visa is common to all 7 emirates, no matter where you enter and where you leave from.  However, question is - who is getting you the Abudhabi residency or sponsoring your resident visa in UAE? This person or company should be in Abudhabi.

Hi,
Thank you very much for your answer.
Have a great day,
Alex,
