Work visa

hello. could someone let me know i am  going to come on work visa to saudi how long is the visa valid (after visa stamping)? due to personal circumstances ( wife's delivery) at home here in india i decide to delay my trip will the visa get cancelled? will there be any penalties if i decide to reapply for job in saudi in near future.

Hi,

Visa is valid for travelling within 90 days from date of issue...

Yup..it takes only 90 days..

if the saudi delegation in india  based on my experience is offering batter post and salary can I turn down the  previous job offer? I got to know this since one of the authorised agencies emailed me details of the salary package. Even for the current post I am offered the difference is 1.5 lakh rupees (9,000 SR p.m). Now I dont know since visa based on previous job offer has been stamped.
I need advice  since I dont want to lie to the delegation who will interview me. If the current visa date is valid for 3 months and my wife is expected to deliver soon.
or should I join the current job.
