What is man by sponsor in Saudi Arabia?

Hello Dear Friends,

I have been selected by an petrochemical company in Saudi Arabia, However they are offering me the other sponsor company visa to travel in Saudi Arabia.

Is it like third party hiring?

Since i was interviewed by the principal employer and the job offer i accepted is also on principle letter head, i am bit confused regarding the use of another sponsor for visa.

Should i go through this sponsor visa. I am working in a very reputed organisation in india on permanent roll and they are offering me a 01 year contract.

Please advise me.

Thanking you in advance.
