A company asks a potential employee to pay the costs of visa. Is it legal?

Hello,

I received an offer letter from an LLC company on 29th November 2021 asking me to be there on 30th December 2021. I'm from Cameroon, they asked me to pay for my visa, work permit, and other fees by a specific company only which they will reimburse.

No interview was made and the mail doesn't tell me from where they took my CV; it says:

The Board of Directors of (Company) accepted and offered you an Offer of Employment to join our Company because your experience and qualifications were found successful and satisfactory. Typically the mode of your selection was based on CV Screening of information on employment datasheet/profile and work experiences once your application is screened and shortlisted (the selection stage may differ from position to position and location of employee). In this case, there is no need for further interviews.

Help me with this, please!

Thanks!
