Withdrawing a job offer after issuing an offer letter, contract and work permit

Hi,

I was supposed to start a job at a new company after having resigned from my old job and completed my notice period.

The new company issued me an offer letter, contract, and work permit, however, they have kept changing the start date, and now, after waiting 6 weeks to start the new job, I’ve been told that the offer has been withdrawn due to a hiring freeze.

I’d like to know what Legal options I have as I have suffered financial loss, incurred visa overstay fees for my partner and child’s visas because I was unable to apply for their new visas.

I am unable to go back to my old company and the only option I have is to return back to my home country as I cannot continue to incur further overstay fines.

What legal options do I have?

Can I claim compensation?

Please advise!
