Can i know?

My friend had loan and credit card can he go vecation this april ? He cannot pay because of interest can my friend hold by the immigration?
Can he take exit and reentry visa

Yes he can unless there's a court order against him

How can he know if he had court?

Simple..

He can check if his ATM card still working, also if he can issue the exit & re-entry visa

But not working and he want only vecation because his mother is died he can go exit re entry visa theres is no problem for airport

No problem .. if he is not allowed to leave they will tell him to visit the court

Can i go for vacation even i have unpaid credit card less than 10k SAR. I was not able to pay because out salary was delayed and our company is under liquidation. I transfer to other company. Please give me feed back.

I believe the same applies to you too.

As long as it is possible for you to get exit & re-entry visa.
