Sorry for late response.
Alhumdulillah performed umrah from Qatar with my parents.
The process is quiet simple, people who are on visit visa in Qatar has to get umrah visa from their home country before arriving to Qatar then they can go to umrah from Qatar and if they wish to comeback to Qatar after performing umrah then they have to get re-entry visa for 200QAR per head which is very easy to get from METRASH app within few seconds.
Re-entry as to be applied before exit from Qatar.
Thanks
