Are there any restrictions or requirements that need to be known to allow my girl friend to visit Oman before she buys the ticket. E.g. must she have a sponsor or book a hotel (vs. indicate my apartment) to stay, etc.
Having worked in Saudi, a single man could not be in the company of a woman unless she was with a married couple. As assumed she could not indicated on the visa she was staying at your residence. In Oman,
Period of stay 1 week. I am Australian, she is Thai.
Thanks
