A visa does not replace the passport it is associated with.
A Valid Passport Is Not an Entry 
Guarantee
Missing Authorization
A traveller may have a valid passport, confirmed flight and hotel—but still have a 
problem if a required visa or authorization is missing.
Visa ≠ Guaranteed Entry
The reverse is also true: a visa does not necessarily guarantee entry. As the 
article's U.S. example illustrates, a visa lets a foreign citizen travel to a port of 
entry and request admission; the border authority decides whether to admit them.
Airline Document Checks
Airline document checks happen before arrival. Passing one does not replace 
border inspection.

Terms and rules vary by country. Check the destination's immigration authority.
Three Different Clocks
These three periods are not interchangeable. Understanding each one 
separately is essential before any international trip.
• Passport validity — how long the travel document remains valid
• Visa validity — when the visa or authorization can be used, subject to its conditions
• Permitted stay — how long the traveller is allowed to remain
A passport that has not expired may still fail a destination's remaining-validity 
rule. There is no universal six-month rule.
