North of London | As others noted what I understand is we let you in without one BUT your country wants to see one for you to get home.
It may be possible without one but a passport will make your life easier.
BTW 4-5 days will allow you to explore a little further than just Niagara Falls if you like and depending on your route you may enter one place and return to US at a different crossing to allow you to see a little more on your trip. | |
