IANAL, but it seems like that Wong Kim Ark’s case and then the Shaughnessy case cover this pretty well.

Wong was a Chinese immigrant who traveled back to China to find a wife. He got married there and traveled a few times to make kids and see Mom and stuff. He came back to San Fransisco this consequential time after the Chinese exclusion act and they tried to refuse him. Spent an inordinate time on the boat because they wouldn’t let him on land. Chinese heavy hitters in San Fran got him a good (white) lawyer and paid his bond and shit. Supreme Court ruled, “Bruh. He’s legal and has been. Let him back in.” Then Shaughnessy was kinda the same thing but on Ellis Island and the govt. wanted him to stay out because he had wrongthink. Maybe he was a communist, I dunno. But again, the Court said, “Bruh.”
