I have signed the offer letter from the agency with joining date mentioned. I have already resigned from my current company. Now I have an another good offer which i want to accept and want to reject previous one. I have send them my all documents to that company but they have not started any process yet. Even my current enployement visa cancellation is not done yet. Now I am worried what should I do? Can that company take legal action against me if i tell them the truth or should I say something else or I have to join them and reject the new offer?
