Single Entry Work Visit Visa

Greetings,

I'm currently working in Saudi on a 90 day work visit visa.  Approximately 5 weeks in the company I work for flew me back to my home country, along with a few other employees to renew our visas.  Even though I still have approx 5 weeks remaining, they wanted to have everybody renewing on the same date.
The problem is on my letter of invitation, it is a 90 day single entry.  Not multiple entry as I have at the moment.
On the multiple entry visa I left KSA every 28 days.
Q1. Do I still have to leave within 28 days on a single entry visa?
Q2. Would I be better off not renewing my visa at all at the moment and fly back using my current multiple entry work visit visa which still has 40 days remaining?  If yes, why?

Any advice would be much appreciated.
Thank you

Number of days will be mentioned if it's a single entry work/ visit visa.

You can return using the multiple and use the single entry once your multiple is over because if you have multiple left you need to cancel that visa and then apply for the new single entry visa...

Talk to your company on this...
