Earlier quoted context omitted.
I think in this case the correct technical term is "denied entry". You haven't passed immigration to the country. Deportation is the expulsion of someone who's actually in the country, past the border, and resident or visiting.
Potato/potahto, really. Good luck getting a visa next time if you've ever been "denied entry". Really, for non-Americans the best advice is just don't go in the first place. Second best advice is just comply with border security personnel. Any tricks like leaving the battery empty, bringing a burner, not bringing a laptop and getting a loaner when you get there etc, they do nothing but raise suspicions.

If they want their walls, let them have them.
