I used a US address for which I have no proof. All I have is an ITIN and an eSIM.
Not many people talk about using an US eSIM, but it was a game changer for me. I have an eSIM from Mint and when I update my address in the Mint app, the roaming IP changes to one in the area of that address. A lot of card applications that failed for me previously, both with and without
VPN, succeeded once I figured that out. I'm not sure whether this mattered for Revolut and Go2Bank though, as I had not tried those previously.
