No, if you are on visit visa you cann't get umrah visa from Dubai, UAE. But you had a possibility to go to Saudi Arbia if you got a via visa from your home country. For now you have no possibility to get the umrah visa from UAE.
Hai I'm in tourist visa and it is expired within one week. Can I extend it? Or can I change and extend it to visit visa? Do I need to exit and come back for this extend? If I need to exit before exit will they issue my visa??
