Friends of state-owned enterprises say that leaving the country needs to be reviewed, especially to a second country. ✅ One trick to solve the problem of leaving the country, as long as the ⌚️ trip does not exceed 7 days. ✈️ Outbound: Home - Hong Kong - Return to the second country: Second country - Hong Kong - Home ❓ Why is it that when you leave Hong Kong, the system cannot review your records of going to the second country, only the records of leaving Hong Kong? 📖 The systems of the Hong Kong Immigration Department and the Chinese mainland border control (NIA) are independent of each other and do not exchange data in real time. In the mainland border control system, only the data of leaving the country (to Hong Kong) to a third country will only be displayed at the Hong Kong Immigration Office. ⚠️ Although this operation can detect that you have not gone to a second country on the mainland border inspection system. But if there is a confiscation of your passport, then you have to think carefully about whether the third country you go to will not stamp your passport. Because the United States has achieved full digitization of I-94 (entry and exit records), it will not be physically stamped. Japan will put a "landing permit" sticker on your passport when you enter customs. So it's important to investigate in advance, isn't it easy to exploit loopholes?
