Under what circumstances can I not apply for a visa for life?

What you should ask is the question of permanent refusal, right?

Take the United States as an example Generally speaking, there are the following situations: one is cheating on visa issues, just like planning illegal immigration but being found out. Or marriage immigrants are found to be fake marriages, or they are found to have deliberately modified their personal data when applying for visas, and so on. Permanent visa refusal was blacklisted for emigrating to the United States. From the day when the applicant was informed of the permanent visa refusal, any form of application to the United States was unconditionally rejected, which means that it is basically impossible to go to the United States in this life.

In the second case, the Immigration Bureau suspects the authenticity of the applicant's information, or the applicant has a long criminal record, and the Immigration Bureau refuses the visa for various reasons. This is very tiring. They don't say that they are permanently refused a visa, but drag their feet until they find a flaw or the applicant withdraws automatically. Generally speaking, they are more patient. It is their short-term goal to delay a case for five or six years.
