Authorize won't accept you as they only accept companies that have a US resident as member with at least 25% stake in the company, 2checkout horrible payouts schedules, Mollie needs bank accounts with IBAN and they don't accept transferwise/wise as payout bank, Your only chance is Stripe don't get me wrong stripe can be an amazing payment gateway but you need to have 'warm' the account you start with small payments you can't scale from the first month or you will get some harsh review and shut you down, and they absolutly hate disputes if you go over 1% they will start with holding money︀ then procceed to kick you out.
