what should i do to get a liscence for an air soft gun in uae?

Well, these are not really classified as a "gun", they are toys that look like guns and shoot plastic BB's at low velocity. The worst that could happen is you might hurt someones eye. I don't think that the UAE would be against toy ownership or require a license or permit??

Good Luck!

No idea, because I don't live there.

Why don't you try asking a police officer or a lawyer, instead of asking people around the world about how to go about getting a license in a tiny Arabic country that many people worldwide have never even heard of?
