Well, your fren seems to have been flying below the radar for a lifetime (aka law abiding, no trouble). Fren likely has ID etc and can likely prove ‘roots’ here. Fren should not worry.
Although Frenparents are not likely to be sent back due to proving roots here with daughter etc, I would highly recommend (LIKE NOW) they get in line wherever they need to go and start the paperwork.
Need to flip their fuckery by MAGA putting a constant array of flowers on the statue. Let them try to stop it, it will be unceasing adornment with every kind of memorabilia. People will forget the plaque beneath all the flowers. And they will not care.
