What to do if your employer defaults on obligations

Good morning sir,

I had been working as a senior site engineer for a good contracting company in Dubai. Meanwhile, I was totally trapped by Al Faisaliyah contracting company, Dubai. The company gave me a better offer and position and told me to join fast.

When I got an offer letter I resigned from the last employer and exit from the UAE for getting a visa from the new company. But the company sent me one visit visa and told me that when I arrive in the UAE they will immediately change it to the employment visa. When I joined here they told me they will change it as early as possible. Last two months I had to work believing their words.

Now I came to know it was totally a trap and they have no labour quota because of 4-month pending salaries to staff. When I realized they are cheaters, I resigned and told them I cannot work illegally here. Also, they didn’t pay me the salary for two months. All the staff here are working with expired visa and same like me.

Now I want my salary. Is there any legal way to move???
