Dispute with employee

Hi

I am Syed Arshad, I am working in a company from almost 2 years in Muscat, Oman. I have joined the company on 25th of April 2017 and and visa is going to expire by 24th of April 2019. My employer has terminated me and gave me a letter of non-renewal of visa and he said my last working day is 24th April 2019. I got some emergency and came to India for one week and shall be back to Oman  by 20th of April 2019. I wish to know is there any chance my employer may cancel my visa before its expiry in my absence, if so what are the consequences while I report to Muscat aiport??

Please help me with right advice.

Rgds,
