Extension of evisa

Hi

My parents are coming to bahrain on 14 days evisa - visit visa. One Tourism company is sponsoring and arranging visa. If they have to extend for a week, whats the procedure. The Tourism company who is sponsoring says they dont do extension of visas and asked us to go to NPRA office in Manama. My question is what are the chances of getting an extension of evisa for a week? will it be successful? and how much would it cost? for extension would they need a sponsor ?

Generally one extension is not a problem.  Go to the NPRA office and they will tell you for how long it will be and how much will it cost.  The days and cost will vary depending on discretion of the officer there.
