Hi, I've got a question but can't find the answer on the internet so far. My husband said that he was going to china for a business trip. He has left for and returned from China business trips a number of times (~3-4 times) within the last 1 month. However, i do not see any China immigration stamp on his passport. Does China stamp on Singapore passports for both the entry and exit to the country? Oh, he is holding on to a Singapore Biometric passport. Thank you so much to anyone can help to answer my question.
