Is it reliable to recruit insurance labels online to work abroad?

I believe that some Asian countries generally guarantee visas, such as Japanese trainee visas, Singapore, the Philippines, Malaysia and so on.

Some people say that sponsorship visas are deceptive, such as Korean and Japanese work visas and Japanese tourist visas.

Other European and American countries, except a few places (such as Saipan in the United States), say that the guarantee is basically a lie.

No one else is a visa officer at the embassy. He promised to vouch for it.
