Nope. Look up the Immigration Act for legal definitions.
You should familiarize yourself with the immigration process. Moving to another country without going through the immigration process does not make you an immigrant. You are a visitor, a tourist, a refugee or an outlaw.
I'm very familiar with the immigration process as well as the dictionary. Immigrant is a person who moves to another country. A driver is a driver even if they're drunk and operate a vehicle illegally. BTW there was no "legal" or "illegal" immigration at the time when the 14th amendment was passed so this is particularly meaningless in the context.
Also "alien" doesn't mean "people who visit the country" like you were trying to imply, there is such a thing as a
resident alien. You can use any cockamamie definitions you want, just cut this liberal snowflake pussy hat bullshit when someone uses the non-PC words you don't like

(I'm kinda enjoying this, I might be a closet Republican).
