What happens if my US-based custodian closes my brokerage accounts, because I am no longer resident in the US?
You will need to establish a new account at a US-based custodian who does provide custody for people living outside the US. Read our US expat case study for a description of how that was handled for one particular client.
Also please note that while some US custodians may allow your account to remain open, they may not permit purchases of new securities, or of certain types of securities. Hence we believe you will want to transfer to an account that offers more investment flexibility.
