What does the 'date of inform' mean on the TM30 portal and how should I fill it out?

The 'date of inform' on the TM30 portal refers to the date you are officially notifying the authorities about your stay. There appears to be some confusion regarding the range offered for this date, but several commenters suggest it can often be left blank if not applicable. Additionally, for the 'stay to' field, it's recommended to leave it blank if your stay does not have a set end date, as the TM30 form will expire on the indicated date.
