Multiple entry visas

Whenever you enter KSA you are allowed a max stay of 30 days. That means you are supposed to leave KSA before these 30 days are over. You can come back to KSA as soon as you like and as often as you like; as long as your visa is still valid (in your case: 90 days from the issue date).

You don't need a special exit visa. Your visa is multi-entry and allows you to travel as you like.

The one visa in your one passport is enough.

@ first check your enty visa in your passport,
and look to (validation & the stay duration)

Before, I was having a commercial visit visa, it's valid for 6 months, but I can't stay more than 15 days, so I should go out ksa - usually expat visit Bahrin - Or extend your Stay duration by your company or (Mo'aqeb).

Thanks for the replies guys, much appreciated
