It’s NOT necessary to book in a 5 start hotel, any hotel would do. All you need is a valid entry visa for the person who is planning to come, nothing to do with Embassy,
just visit any hotel & make a booking for the days he is gonna stay & ask them to apply for the tourist visa. it will cost you Qr.250/= for the visa.

P.N.
The person has to stay in the hotel until he leave’s Qatar, if not FINE Qr. 10000/=
