QATARI AUTHORITIES ARE VERY KIND AND GENEROUS. AS LONG AS THE VISITOR HAS A PIOUS PURPOSE, I DON'T THINK THEY WILL BE DENIED FOR ENTRY. JUST MAKE SURE YOU HAVE A RETURNING TICKET PLUS THE ADDRESS AND QATARI ID OF FRIEND/RELATIVE WITH WHOM THE VISITOR WILL BE STAYING IN QATAR. "ALL THE BEST" THE PROCESS IS VERY SIMPLE AS LONG AS YOUR LOVED ONE'S CAN CONVERSE IN ENGLISH, HE/SHE SHOULD NOT FIND IT DIFFICULT TO OBTAIN A VISA.
