Claiming unpaid salaries from employer without work visa

I overstayed in Dubai just because of my ex-employer negligence, after failing to proceed my visa stamping on my passport.

My ex-employer issued only a pink copy visa for me. Although I had informed my ex-employer that time was too short and begged to complete the visa process, but unfortunately, he could not do so.

My 10 months' salary is also pending at their side, so I don't have money to pay off my immigration overstay fine. But in spite of all the hardship, I went to the immigration department at Al Aweer to waive off my fine.

I was trying to avail any sort of discount to clear my overstay status, but the immigration department did not listen to my full stance and sent me to the temporary immigration department, and gave me 2 days to arrange AED 20000 as my fine.

I said to them I have only AED 10,000 and they refused to take it. Now, my previous company paid the fine.

Just let me know if I can come back to Dubai and if there's any chance to recover my pending salary.
