A visa is an annotation or stamp from the sovereign authority of one country on the passport or other travel documents of its own or foreign citizens, indicating permission for them to enter, exit or pass through the borders of that country, or can be considered a type of endorsed proof issued to them.
Only the entry and exit management authority of a country can stamp a visa onto the passport of a citizen from another nation.
Such entry and exit management authorities include, but are not limited to, foreign consulates, border checks, and immigration offices.
Given that Xiang Shan's passport was obtained in Beiping, it can be basically assumed that the Republic had already notified the embassies of those countries when producing these passports.
In other words, the Federation was aware of and acknowledged their arrival here.
Jing Hongtu glanced at Xiang Shan with approval, nodded slightly, then continued to walk forward to Professor Zhou, grabbing him and whispering something.
