Dear Sir/ Madam,Many Greetings! I am a Christian Pastor and I am learning Korean language in Seoul and on the eve of this
Chritmas, I want to visit China and Hong Kong for 5 days of each country and then go to Pakistan to meet my family and after that come back to Korea, but I do not have 6 month valid Allien Registration card because I am an Allien Card for 3 month and and after 3 month i need get the new one. So my question that it is possible for me to obatin Chinese visit visa and the short visit visa of Hong Kong.
