Which is more serious, visa refusal or repatriation?

It's a little hard to say what's more serious.

Because, whether or not to grant entry and visa is the country's immigration officials, they have absolute power.

What is absolute power? Based on its regulations and experience, if you think that someone's entry may affect national security, you can refuse.

Denial of visas, and many refusals, means that it does not constitute entry conditions at all, and the first level is blocked.

Repatriation refers to obtaining entry permit through legal (or illegal) means, but being stopped when the second/third customs are suspected.

The second level here means that the immigration officer who enters the customs thinks the visa in front is suspicious.

The third level here refers to being arrested and repatriated for various illegal incidents after entering the customs.

It can also be said that each level has its own conditions and discretion at that time, which is the result of different situations.

For example, a person who abides by the rules at home, but commits an unacceptable law in another country, is repatriated.

One is only in China, and he has a record that he is not allowed to go to that country, so he was refused a visa.

So, it's hard to say which is more serious, it depends on the situation.
