I am terminated from my company and my visa was...

Please note that the UAE governement announced that all visas, expired UAE residency, visit visas to remain valid until the end of this year (2020)

The residency visa of expatriates, inside or outside the country and expiring on March 1, to stay valid until the end of the year.

Same thing for Tourist Visas.

This decision is applicable to those whose visas have expired after March 1 this year.

The visa fees exemption is for all types of entry permits which expired during the flight suspension, and the exemption time frame is from March 1 until end of 2020, or untill the flights may become available, whichover happens earlier.
