After signing the offer letter and the contract, the employer cancels the contract

Hello,

I am an American expatriate who was offered a job in a Dubai school. The employment offer and contract were both signed. The school asked me to come to Dubai on a visit visa and said they will process a work visa once I arrive.

I arrived at their provided accommodation, but 2 days later, they canceled my contract stating I am no longer needed because of the low number of students in the class.

They are now asking me to move out of the apartment in 1 day and go back which is all against the contract. I contacted MOHRE but they said that a case cannot be filed because the school did not start the visa process.

What are my options here? I am left with no work, no housing, and still not compensated for even the air ticket here which was all promised to me.

Surely, the signed offer letter and the contract from both parties has some legal standing. I am willing to prolong my stay to take this school to court.

Please help.

Thank you!
