Relatives joining visa 2019

Dear All,

I am working in muscat. I got "relatives joining visa" for my wife and children. It is two years multiple entry visa. Visa valid only 3 months. Visa will expire on April 30. So I had planned to bring my family on April 1st week. But non omanis cannot  enter to oman from today due to covid 19 spread. So I am worrying about my family visa validity. Can i get extension of my family visa validity?

My guess during this corona virus situation, no penalties will be applicable on the individuals that were trapped in Muscat and their home countries have their airports officially closed e.g. India
