Old passport queries for visa ( Saudi )

Dear Sir/Madam

Greetings

I am a Doctor recently , I have been selected by Ministry of health Saudi Arabia. I have a valid passport but my old passport is missing stolen . I would like to know whether for purpose of job visa as doctor , do I need old visa ? If suppose I don't have old visa what is the alternative , if they insist on old visa.

I would be grateful of you could answer my queries.

Regards
Dr. Mohamed Arshi
