just thought people should know this, it may help...
yesterday i went to renew my visit visa, from 30 days for another 30 days, went to the typing shop ,paid the fees, then went to the immigration dept,
i was told 30 days was now the limit and no extensions were granted beyond that, the rules seem to have changed again,
i asked if all i had to do was leave and come back, the immigration chief said yes, no problem, just go out and come back in again, but 30 days was now your limit! i have been here for a year or so now and thought it might be because i have been coming and going , but the didnt even look at my passport, and i also checked with the head of immigration at that office, it seems that the rules are changing every day!
i have also left out of sharjah apirport before now and was warned that i must really exit from the Emirate that i entered, that took 4 days to sort out on the UAE computer system!
