The issue with immigration from Latin America is that the volume has been high enough that their original communities and cultures survive in tact, and those cultures involve a lot of socialist policies. It's Republicans not wanting to import people who vote for Democrats.
That's not really the case for immigration from places like Vietnam who assimilate much faster, but if they treat people differently like that then they get accused of racism and sued over it. So if they want to stymie net-Democrat-voter overall immigration by being pedantic about old forms then they have to do it uniformly.
> U.S. officials have been working behind the scenes to convince the Vietnamese government to repatriate more than 7,000 Vietnamese immigrants with criminal convictions. They have all been ordered removed from the U.S. by a judge.
> The U.S. government is trying to deport Vu over two criminal charges of assault and larceny dating back to 2001, even though both of those convictions have since been vacated.
> Vu was born in Saigon in 1967. His father was a U.S. serviceman fighting in the country, and he barely knew his mother.
> Now, in Boston, he has a steady job, a longtime partner and two U.S. citizen children. He doesn't want to return to Vietnam, but he might not have a choice.
