Non-Exempt Visa after Work Permit

[usausa]

Hello- I have questions about my possibilities of entering the Kingdom after having a Non-B and work permit. USA Passport. Below are dates

 

Sept 15- enter Kingdom on 60 day tourist visa

November 12- 30 day extension

November 26- 90 day Non-B received in Hanoi (expiring Feb 25)

Two Re-Entry- both with individual permits- Dec 21- Jan2, Jan 14- Jan21

Hopefully will extend Non-B and obtain work permit by mid-Feb

*New Passport to be ordered*

 

Traveling out of country March 7-March 27.

 

Questions: If I leave my job and my work permit/non-B is cancelled how many more entries will I have on a 30Day Exempt? Basically I need April- beg of July with 2-3 entries on a tourist. Will this be okay?

 

TIA!!!
