Opening an account seems manageable, but what about keeping it active over the years? Do EMIs and banks require constant updates, high balances, or minimum transactions?

Good question. Maintenance depends on the provider. Some EMIs require regular activity, others are more relaxed. Traditional banks may ask for annual proof of address or source of funds, especially after 1-2 years. I’ve been maintaining two accounts — one EMI and one bank — for over three years now without major issues. The best way to stay ahead is to follow threads like this one in Offshore Banking. Users update each other when providers change their policies. That’s helped me avoid surprises.
