>I don't have a "legal name". Sounds like some sovcit bullshit.

Considering every country has passports and passports all have the person's legal name on them. And thst the passport standard only supports having one name with a primary and secondary identifier. You must be mistaken.

Not everyone has a passport. And people with strange or no name may have passports with names that are not theirs.

But it does mean that the country has a way of picking a name to use on one.

They might have several different passports from different countries.

It's also fairly common for instance for women to have multiple names from their marriage(s).

Use the same name as the identification you are submitting. It's not that complicated.
