Anyone know if the 'admitted until' stamp on the departure card has any significance at all?
Contrary to last time I went through immigration, she didn't put on a date on that.
The one in the passport perfectly fine.
Cheers!
TLDR : Answer Summary
The 'admitted until' stamp on the TM.6 departure card is now mainly for record-keeping and tends to coincide with the entry stamp in your passport. The most significant date to consider is the one stamped in your passport, as that dictates your stay duration.
