WORK VISA FOR SAUDI WHILE ALREADY WORKING IN BAHRAIN..

I have commented on this multiple times.   To keep it simple:

1) You can only process your Saudi visa from Bahrain if your sponsor assigns a visa to the Saudi consulate in Bahrain.   However, this is not very common as whenever an employer gets a quota in Saudi, they assign by nationality and profession to home country.  This is why in most cases, you have to go back to your home country for Saudi visa processing.  In the event, they can do that, they would need to assign a visa for Indian nationality to Bahrain and then give an e-wakala to an agent to deal with VFS.  I had my visa done from Bahrain the same way.  Be aware that your current employer / sponsor NOC would be needed by Saudi Embassy
2) It's called Saudi visa medical and you can do it at Ibn Nafees.  Reports have to be submitted to Saudi Embassy
3) Explained above.  I don't remember the cost.  I think it was around 100 or so BD.  The test are the standard GAMCA ones but with stool and urine test both
4) Don't understand what you mean here

Thanks for your swift reply.Appreciated....
reply to 1) Answer
If we hire an Agent in Bahrain can he handle that saudi Embassy and process for visa of saudi arabia.

4. How about MOFA number means after issuing visa and before attestation on saudi visa an agent will issue an MOFA number which will be generated by some amount .This number along medical approved copy ( FIT status) is sent to Embassy of Saudi in Mumbai or Delhi for stamping and after stamping is done. we can book ticket for Saudi Arabia.

1) I already clarified.  An agent cannot do anything unless a) A visa is assigned by your employer to Saudi Embassy in Bahrain and b) Employer issues e-wakala to agent

4) You are now talking about issuing the visa from India.    I have already clarified that you either issue it from India OR Bahrain.  You can't do medical in one jurisdiction and send report to India.   Either you do whole process in Bahrain or whole process in India
