If there is an alien in real life, how can he hide his identity?

Aliens live on the earth, and if they don't have special abilities, they need to hide their identities and live in seclusion. If he has a special ability, he can make himself have a legal identity and look like others, because now, whether renting a house, working or going to school, he must have a legal identity, and it must be filed by the police station, otherwise he can't move, and he can only live in a sparsely populated place without corresponding identity authentication.

Without legal status, it is almost impossible to live like an ordinary person. When renting a house, people will know that he has a problem as soon as they check the accounts. If you can't even get a bank card to work, the company must know that there is something wrong with him.
