I was on H1B from April 2014 till Mar 2017. From Mar 2017 till today I am in India. Now my employer is ready to file H1B petition to reuse my remainder time. The problem here is they are saying that I can stay only till Apr 2020 ( 6 year max from April 2014) but shouldn't it be for period (6 years - period from April 2014 to Mar 2017) which is around 3 years as I only stayed in US for 3 years.
