I find it very unlikely that they will insist on foreign transcripts or know about them if you don't tell them. That said, since admissions is not competitive, I don't see why you wouldn't submit them for whatever good they might do. Even if you only get a handful of transfer credits, those are credits you don't have pay for now. Also, submitting a college transcript will should make a high shool diploma unnecessary.
