Yes, I agree with you that TPS is very confusing. Some of the things are very simple, but we are making it confusing. Just don't listen to one person, rather get the information from everyone, read online, go to forum where people who already got TPS(from other countries), talk about TPS.
From my experience, college advisor/DSO/International office are the least knowledgeable on this matter. TBH they have no idea what they are talking about. Most of the ones my friends/Saja people talked with had no idea, but we can not judge all.
Best bet is to wait, know it in deep and apply. Even Nepali lawyers are not 100% confident about it.

Each case is different, so it needs to be treated differently.
Good Luck
