"Finding someone" is the entire assignment?? So the assignment was to
FIND an immigrant?

I don't know anyone who is allowed, nor do I see it as a requirement or necessary, to "wander around willy nilly" talking to strangers. Nor do I see it as necessary or required for a parent to go through their questions
extensively. Two kids in college, and one a Jr in HS, and it's always been a HUGE requirement that they do their own work. I've rarely (not "never") helped them with anything, and somehow they've managed to do their own work AND get good grades. They're also very capable, independent and self-reliant. You stated that FINDING someone IS the assignment. Again, I disagree. I DON'T agree that it's not difficult to interview someone, even with the questions (which I would expect at this age). Interviewing someone is more than reading off the questions...I'm going to ASSUME that they need to get the answers and do something with those answers...a paper? An essay? A project? I think
that's the assignment. In the scenario you present, I agree.
