I have my H1b visa/I94 valid till Jan23rd 2017.
Employer applied for Extension,( later upgraded to premium) and petition
is approved on Oct2016 itself.
extension validity starts from Oct2016 to Oct2017. ( approved for 11 months appx)
Question is, why I’m loosing almost 4 months of valid visa period and why it is
extended from oct 2016 ( date of approval) instead of Jan2017, as i have valid visa till Jan2017 before extension?
