特區護照免簽證逗留超過3個月有冇問題?

It is not suggest to overstay. First, you may need to pay some penalty when you leave the country. Second, when you want to go to same country again, they will question about your intent of staying there. If you only overstay for a couple of days, it is easy to explain, otherwise, there would be a bar on your entry, meaning they will not allow you to entre that country. The bar would last for a period. For some countries, it would be 10 years.

可能會被列入黑名單，下次入境就有困難。
