Extension of residence permit by a month

by Abe

My UAE residence permit is expiring this May. I was wondering if I could get a month's extension (without having to renew my visa) and exit in June. Is there a provision for such an extension?

If so, can I do it on my own or must I approach my current employer to take the procedure forward? And what would be the charges applicable?

Thanks!
