See, I went to the NY consulate (also as a day trip with the family) and they DID ask for proof of finances. However, I had mine & my parent's bank statements, plus a letter of support from them, and they were fine with that. I didn't really get grilled, even though I was coming off a BUNAC stamp in my passport, which probably looked a little funny. They simply asked the routine questions, verified the date I needed the clearance for, and voilĂ ! Come back at blank time and pick up your passport. Easy-peasy.
