Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Input: Consider Input: Looking at website of Guyanese Embassy in Brasilia, Brazil I'm not sure if they issue visas to foreigners:


  We advise that Brazilians do not need a tourism visa to get into Guyana (...) Fees: touristic visa - R$45,00 (...)


Since they mention that Brazilians don't need a touristic visa and yet publish its price, I understand they issue visas to foreigners. There's also a visa form in English available on their website.

On the other hand, according to Polish MFA (information available in Polish only)


  You can apply for a visa in Guyanese Embassy in Brussels or Caracas, Venezuela


My question is, as a citizen of Poland and resident of Brazil, can I get Guyanese visa in Brasilia, Brazil? 


Output: Can Polish citizens get a visa to Guyana in Brazil?


Input: Consider Input: Do gas station in small towns or rural areas in Northern Ireland and the Republic of Ireland accept credit cards and debit cards for payment?

Input: Consider Input: I'm a permanent United States citizen (by birth), but I don't have an SSN. I'm also a foreign citizen. My employer outside of the US wants to send me to work into the US for client on-site by asking for a work US visa that would be put into my foreign passport.

Is it legal to obtain and enter the US as a foreigner with such a visa, being at the same time a US resident? Can I enter the US as an American, but work as a foreigner?

I found this reference:


  A foreign national or alien entering the U.S. is generally required to
  present a passport and valid visa issued by a U.S. Consular Official,
  unless they are a citizen of a country eligible for the Visa Waiver
  Program, or are a lawful permanent resident of the U.S. or a citizen
  of Canada.




Output: Is it legal to enter the US with a US visa while being a US citizen?
