H1B : Travelling back from India : Visa Validity

[rkohli45]

Hi,

I am planning to go to India in Feb 2018 and will be back in Mid March 2018.

I have H1B Visa till June 2018.

Is there any issue that we should be having at least 6 months of valid visa to Enter United States ?

Or is this constraint has been put by any airline ?

Can I travel back normally with Any Airline in March 2018 ?
