Is it legal for the company to ask me to pay the recruitment port fee?

If you don't approve, the job may be gone;

Then you need to pay the recruitment fee of the port yourself. First of all, you can judge that this is not a good job. Secondly, you can judge that this employer is not a good one, and maybe it is still a fraud company.

If it is a company that already has a job, it is neither reasonable nor legal to force workers to pay the management fees of the company, if there is no such agreement before. Just don't accept it
