Hi, In my previous company, in 6th year extension i got 3 years (till 2018) based on the approved i-140. I transferred to new company and i got H1B till Nov 2016 based on the previous company i-140 and current company client letter. Client project duration is less than one year and approved only one year. Still my previous company is not withdrawn the i-140. In current company,Perm processing is started and it seem perm labor is going to be submitted on March last week. Suppose if I-140 is not approved before my H1B expiration date and if my previous company withdraws the i-140, Can i extend my visa status for additional one year periods till 2018 (In my previous company i got H1B till 2018)? is it possible?
