Visa for parent in laws during June to September months..

Hi,
I wanted to apply  visit visa for my  Parent in laws by this month but the HR of my organisation said that the visas will be closed till Hajj ends...
Is this information correct or still the visas will be issued by the authorities.

It's correct...

or unless you work for a government entity, you can still get it.

You can go to Istiqdam, from there you might get.
