I am a Canadian Citizen , have my US LLC in the state of Wyoming. I have US phone # , US registered agent and hence the address where I get my mail and have my EIN , haven't opened a Bank account yet. In the process of doing that. Interactive broker requires me to have proof of address other than the registered agents address . What can I provide as proof of address for the Business ? I provided them with the operating agreement but they rejected that. Please advise
