Will there be problems? (Girlfriend visiting)

[Misiu]

Hi guys,

Situation:
Girlfriend (21) from Poland (visiting for 2.5 months)
She's taking a year off from school

My questions:
-She's from a visa-exempt country, but will they give her a hard time since she's young and doesn't have a lot of money? Maybe thinking she may be here to work?
-Also, when they ask for reason to visit, does she tell them to visit boyfriend? Some people say tell the truth, others tell them visiting family friends.

Thanks in advance.

Any advice?

1. Proof of funds to support her during the visit
2. Return ticket that shows she intends to go back
3. Explanation for how she is able to get away for 2.5 months

If possible, I would also include proof that she will be resuming her studies in a year. If by any chance she has already paid her tuition for next year, include proof of that as well.

What would be considered sufficient funds in this case?
