Visit Visa for Father who left on exit-rentry and didn't come back

Hi,
My father was here in Saudi Arabia for more than 30 years. He went home 18 months ago on Exit-Re Entry and never came back due to health reasons. I want to apply for a visit visa for both my parents. My father told me that one can not come back before 2 years. He also told me that even if I get a visa for them the Saudi Embassy back home will reject his and my mother's visa cos he didn't go on Exit.
A friends told me that the Passport Authorities in the Airport might also refuse to give entry to my father upon arrival here.
I want to know if there will be any issue if I apply for a visit visa for my Father and Mother.

Regards

As far as I know, an automatic ban of 3 years is applied on people that leave on exit/re-entry and do not return back on employment visa. I also believe that visit visa does not include in this ban but your father can pickup the phone and call the embassy.

Thanks for the reply. That is one of the option to get in touch with the Embassy back home.
