Is my Oman visa still valid, if my name is changed after marriage and I have my married name in my passport?

Dear All, I am working in Oman and Recently I married and planned to bring my wife here on 31.07.2014. I applied Visa and I got it in hand. Now with the advise of colleague we applied to add my name in my wife passport. In that Process we received passport with my name in her passport. But they changed her surname also in her new passport. But the Existing Visa is with Old Surname. Already I booked Tickets and all. we have old and new passports with us. We received her new passport on 20th July 2014. Her visa is ready by 22nd July2014. Is she can able to travel to Oman on old family visa which is in hand or we should apply it again? Can you please help me to get some idea whether I face any problem in Airport? Thanks in advance for your reply. Regards Satish
