The settling-in allowance promised to enterprises at the time of recruitment has been in arrears.

Hello, I suggest you save the recruitment website of the company at that time, and you'd better make a notarization to save the evidence. In the communication with the company, pay attention to keep evidence such as mail or telephone to prove that the company has promised to give you a settlement fee. After you do it, you can ask the other party to pay the resettlement fee for the first two years. If not, you can apply for arbitration.
