Does your wife have a birth certificate? How about a passport? You are scaring yourself (and her) for no reason. Unless she's picking weed or hanging out on corners looking for day work or working for known employers of illegal aliens she isn't going to be harassed just out shopping.
Every person in the country illegally needs to repatriate themselves, preferably voluntarily. They are all criminals. I don't care how nice they are or how long they've been here.
Once we've gotten rid of the 20 million Biden invited in to drain our welfare system, we can talk about legalizing but NOT EVER making citizens of, people who've been here for more than 10 years who have no criminal record. At this point, we're only 100,000 in to the backlog. The easy pickings are gone and now ICE is going to places where illegals congregate.
ICE also needs to start arresting mayors and governors who are ordering their people to not cooperate with ICE. Harboring criminals is also a crime. So arrest the employers and and apartment building owners who harbor the criminals.
