Hi there.
I received the TM30 related email telling me I needed to register on the new page. It took a few goes but I managed to register without much trouble. I got the confirmation email and password etc.
The question is do I need to file a new TM30? There was no suggestion that I had to, only that I had to register and I provided the necessary documents.
TLDR : Answer Summary
The user inquired about the necessity of filing a new TM30 after receiving a registration confirmation for the updated system. Responses suggest that if a TM30 has been previously filed, there is no need to submit another unless traveling. It’s recommended to verify specific policies with the local immigration office.
