During the pandemic, the family moved into a house that prosecutors say was part of a marijuana trafficking operation.

Yang was among 26 people indicted in a sweeping federal case in 2020. It alleged Yang helped count and package cash that was mailed to marijuana suppliers in California. Prosecutors found bags of cash taped between pages of magazines, according to a complaint.

She took a plea deal and served 2 1/2 years in prison. She said her attorney incorrectly told her the plea deal would not affect her immigration status as a green card holder. But her legal permanent residency was revoked.

At the end of her sentence, Yang was transferred to an ICE detention facility in Minnesota. There, at the advice of another attorney, she signed a document agreeing that a deportation order would be entered against her in exchange for being released from detention.

Despite agreeing to be deported, she and her attorney believed it wouldn’t happen, since only a small handful of people are deported to Laos each year

Sounds like she got involved with something she shouldn’t have as a green card holder, and then took some crap legal advice that didn’t account for an aggressive change in administration/policy.
