Travel to USA within 6 months of passport expiry

[immiqueshelp]

Hi,

 

My mom is travelling to USA on visitors visa in Feb 2016 and flying back in April 2016.Her passport is about to expire in May 2016. 

 

Would this cause any issue at POE in USA or Would airlines not allow flying within 6 months of passport expiry?

 

Please help.

 

Thanks,

Rohith

chances are high that airline will cause issue. passport validity >6 month is like unsaid international standard.
