ISA account for non resident person

I am a British national and have been invested in an ISA since the late 1980's. In 2002 I accepted a job offer in Vietnam and am still living in Vietnam, The GOV.UK page for ISA's notes that ISA's can still be held after moving abroad except that no further money can be added. My ISA was originally with Alliance Trust but was moved in a group transfer to Interactive Investor. I passed all the identity, source of wealth and money laundering checks in 2021. Interactive Investor have now informed me that my account will be closed in 90 days. Can they do this in view of the government rules allowing ISA accounts to be retained when moving abroad?

Hi

We are unable to answer your question, as it is not a question on tax.  
You would need to take this up with the ISA provider or seek professional advice.  
You can transfer the ISA to another provider, even if you are not resident in the UK.  Please see Individual Savings Accounts (ISAs)

Thank you

Hello. I have a couple of questions. My first question is to do with residency. I am a british citizen, born in england, my parents also. I lived in croatia for 12 months, but not continuosly. I came back for a couple weeks at a time to visit family. I then returned home in february and stayed in england until the middle of march. I am now travelling asia for 7 months. Does this class me as a non UK resident? I live with my parents in the UK and I do not own any houses abroad or in the UK. 2) I would like to put money into an ISA, but you have to be UK resident to do so. That is why I am asking. Thanks!
