I am a Canadian citizen who is currently working in the UK on a Tier 5 Visa. My visa is valid until January. My total time in the UK will be about four months.
When I arrived at Heathrow, I saw a border officer and received a stamp on my Visa. Now, I plan on visiting home for Thanksgiving (October) and coming back after spending seven days in Canada.
As a Canadian citizen, I can use the eGates at Heathrow. However, I am not sure if I need to get my passport stamped again if I reenter the country during my Tier 5 visa. Would it be safe to go through the eGates, or do I absolutely have to have a stamp in my passport upon reentry?
