I have offices that I have an affinity for

I would like to know how VISAs are tolerated if you were an executive of a large corporation (or even small corporations because they should be subject to the same laws in a free society like America, right?) and they needed to visit an office in a foreign country. Donald Trump worked alot of the time when visiting his hotels of his in other countries because he was running a corporation or corporations, and he didn't have any problems with VISAs in foreign lands. This is contrast to the types of laws America purveys sometimes, like ones in which "work" has a broad definition and people don't need to be making money to be considered working and deported from the country. Yet if a TransCanada executive from Canada came to the US to oversee the construction of Keystone XL from an office they had in the States for a few days, they would have no issue, even if it was just a Business visa.

Therefore, every executive from every corporation should be able to do the same and the same sort of laws shouldn't be interpreted in a different way for some corporations vs other corporations.
