After submitting an application for an Australian student visa (subclass 500; for a 7-month university exchange), I was prompted to undertake a health examination. Due to my medical history, there is a moderate/high risk of failing the health requirement, and therefore having the visa refused.
To prevent complications during future applications for short-term visas for other countries, I'm considering to cancel my university exchange and withdraw the visa application. Doing so would suck for several reasons, but perhaps it's better than having problems with future applications.
Q1: How could an Australian visa refusal due to 'medical inadmissibility' impact future (short-term) visa applications for countries other than Australia?
Q2: Would withdrawing the current application be a good solution to prevent negative effects on future (short-term) visa applications, or would it be ineffective?
The medical background is outlined below for context.
Cheers I look forward to your opinions
Medical background: I've had three brief psychotic episodes over the past eight years, all of which have required hospitalisation. In-between episodes (and for the past three years) I've had perfectly normal mental health. For various reasons I have never sought treatment after those psychotic episodes (though the present situation has motivated me to do just that!), and thus haven't been diagnosed with Bipolar or any other permanent mental health disorder. Nevertheless, I expect that both the history of psychoses and the lack of subsequent treatment increase the visa refusal risk.
