They just check whether you have RP stamp on your Passport and the title (post) on your(your husband's) ID card. Also they check were you are going to stay in UAE. That you have mention on the form. One form is enough for one family. Before that you have to buy 100 dh card per person. Then Fill up the form and go to immigration counter.
That's all

Whenever I find the key to success, someone changes the lock.
