Q: Can someone enter the United States of America in February 2014 and spend two weeks if their visitor's visa expires in April 2014?'
A: Yes! If your visa is valid on the day that you travel, and your passport is still valid for at least six months beyond your intended stay, you are good to go. So, if you plan to travel on February 28, 2014 and leave March 14, 2014, your visa must be valid at least until February 28th, and your passport must be valid at least until September 14, 2014.
A common misconception is that the visa validity indicates how long they can stay in the United States. If a visa is valid, it means that you can travel to the US and present yourself to Customs and Border Protection at the port of entry. The officer at Customs and Border Protection then determines the maximum amount of time you are allowed to stay in the US.
So, if you have a visitor's visa that is valid for 10 years, that doesn't mean you can stay in the US for 10 years. It means you can use that visa to travel to a port of entry as many times as you want within that 10-year period.
For each trip, the officer at Customs and Border Protection at the port of entry will stamp into your passport the authorised duration date of your stay. If you travel on February 28th, and your visa expires March 1st, for example, but the custom's officer grants you a maximum stay of six months, you can still stay for your full two-week vacation.
