When going to Japan or Korea with a group, do you apply for a visa by yourself or with a group? Do I need to return the deposit or something?

If you travel abroad, your travel agency will give you a visa. If you just go out to play, there should be no refund of the deposit. As for civil servants, it is very troublesome, and it is very troublesome to ask the unit to prove something.

If you travel to Hong Kong as an individual, there are: if you are residents of Guangdong Province and 23 cities in the mainland (namely, Shanghai, Beijing, Nanjing, Suzhou, Wuxi, Hangzhou, Ningbo, Taizhou, Fuzhou, Xiamen, Quanzhou, Tianjin, Chongqing, Chengdu, Jinan, Shenyang, Dalian, Nanchang, Changsha, Nanning, Haikou, Guiyang and Kunming). You can apply for free travel to Hong Kong and Macao. Others who come to Hong Kong in their personal capacity must obtain a pass to and from Hong Kong and Macao issued by the relevant public security organs in the Mainland and one or two valid "individual travel" endorsements. Otherwise, you can only travel to Hong Kong by "traveling with a group".
