International student, complex study history, looking at TESU BA Psych

[davewill]

Update: I contacted Monash College for my transcripts and was informed I had a debt with them I needed to repay before they'd send them. ... However, this does create further problems for proving my eligibility. What's the ideal way to demonstrate my prior study if I can't get transcripts for the largest chunk of it?

Eligibility for what? TESU admission is universal, so you won't need it there. If we're talking about employers, you can still say you went there (since you did), and they may be happy with just your say so, or with an unofficial transcript if you have a copy. If the payback is there, you could always decide to pay the debt when the time comes, if you just have to have an official transcript.

If you don't think the debt is valid, you could try appealing or suing them.

You're lucky you don't owe a school here in the U.S. TESU (and others) often insist on all official transcripts before letting you graduate and you could find yourself stuck. The school in Australia is outside their view.
