Exit Permit from Employer!

Can somebody in forum  assist me to understand the process of Exit Permit:

1: Is there any limit for exit permit per year?

2. Can Exit permit be obtained every week?

3.  How long the approval process of exit permit typically takes?

4: Hope its online process

Regards

per new law,, its online service, the new law will take place at 13 dec this year,
it will take 3 days, (and in emergencies less than that) and its valid for one week..
there is no limit, i have some friends spend every week end in dubai,

in special cases, (companies which have employees have to travel frequently there is a yearly permit, you can ask your company to get one, but it needs a special approval)
