Yes, I would advise the OP's daughter to be extremely careful.
This Canadian woman working legally in the US was detained for a fortnight, moved around to different detention centres and actual prisons, in chains in appalling conditions. The stories of the other women, none with criminal records, that she met in prison are fairly chilling -- women detained for things like having overstayed three days at the end of a student visa, left the US for their home country for years, and then flew to the US for a holiday years later on a tourist visa and were detained.
And this is a white Canadian woman, with a Canadian passport, no criminal record, a work visa, a lawyer, friends and family advocating for her, a politician lobbying for her release, lots of media attention etc etc.

I also know the family of Donna Hughes-Brown who has lived legally in the US since the 1970s, is married to an American army veteran, had her children and grandchildren there, and who was detained in isolation after she flew back from visiting family in Ireland because of writing a bad cheque for $25 in 2015, for which she'd done restitution at the time.
Another Irish guy overstayed his US holiday visa by three days after injuring his leg and being advised by doctors not to fly till the swelling went down, and was detained at the airport while trying to leave, and imprisoned for three months.
