I am not sleeping too well because my parents' caregiver IS leaving after all. Those signs we spotted a while back were truly an indication she was leaving. I didn't know why because the man who owns the board and care never tells us the truth. I suspect he never tells anyone the truth, ever.
According to the caregiver herself, he deceived her, promising to sponsor her in her bid for residency and citizenship, but he never did. That was 7 years ago. Now immigration has caught up with her, and she was allowed to apply, via her brother, who is a legal resident, but she cannot work anymore for a while. Of course, she still needs to work, but it won't be via legal channels.
She wanted us to let her work for us privately, and that would suit us fine, but we must be inspected by VA, and under the table won't work for us. So someone new, probably someone without experience, will take over. That makes me very nervous, so I am on the lookout for a new place, which I might have to move my parents to at a moment's notice, if something egregious happens.
