The (IMO poorly written) article implies that not only are Vietnamese origin criminals who got here before 1995 eligible for deportation, but ALL Vietnamese immigrants who got here before 1995 are as well.
Other sources like https://qz.com/1493761/trump-is-preparing-to-deport-thousand... indicate that the stated reasoning seems to allow that, but Trump's administration hasn't made itself available to confirm.
If this isn't a simple misunderstanding of what Trump is saying, then this is going to be a huge issue. There are a lot of people affected.
