Hi! 
I have two questions relating to the D10 visa and E7 visa. Thank you for your help.

1. I have heard it is possible to do an internship on the D10 visa for up to 6 months with a company that is willing to sponsor an E7 visa. However, I've also heard that those who came from E2 visas are ineligible to do these internships, is this true? If I am an E2 looking to later transition to E7 am I totally unable to do an internship first with a company willing to sponsor my visa later?

2. Some E7 work codes require a bachelors degree + one year of work experience. Does this work experience only count when it is after graduation or does work experience before/during college also suffice? 

Thank you very much ^^
