Your visa lapses 6 months after exiting UAE

Q-I was working in a school based in Dubai and left for Pune, India on December 21, 2017 on vacation. In India, I lost my passport and therefore, I had to approach the passport-issuing authority for them to issue a new passport. The lost passport had my UAE resident visa affixed. I have a picture of my UAE visa page stamped on my old passport, employment card and emirates ID of UAE.
Upon re-issue of new passport, I requested my employer to send a letter along with copy of my visa addressed to UAE Embassy in India stating that I am an employee of the Dubai-based school and that I had lost the passport. Based on this letter, the UAE Embassy in India would affix the UAE residence visa on my new passport. But my employer did not send the aforementioned letter and replied to me by email stating that they had hired another teacher and informed me that they will not help me regarding this matter. Now, I want to come back to UAE and work for another organisation.
You may request your employer to settle all your dues and cancel your visa, so that it will enable you to look for a new employment in the UAE. Alternatively, your visa will automatically lapse after six months from the date you left the UAE.
