The UAE rules regarding the second marriage for an ex-pat

Hi,

I want to know the UAE rules regarding the second marriage for ex-pats.

I am a Pakistani national, already have a wife. Now I want to do second marriage in the UAE with a Syrian refugee girl. Can you please let me know the procedure involved in it?

Can I get my marriage registered in the UAE? And can I sponsor my second wife?

My employment visa in Sharjah.
