I am from Brazil and facing a similar problem. If you stay away for 1 year you are automatically a non resident. And also unable to keep bank and brokerage accounts there. My wise still works and have some other international alternatives such as Advcash and Dukascopy. One thing you can also do is perhaps opening a company for banking purposes. Like an UK LLP with your partner or an US LLC.
