I have a stamped H1B in my passport (2015 to 2018) and not traveled to US. After stamping of one month USCIS reopened my case and revoked the case after 4 months. The reason for revocation is the site visit to employer by USCIS. Shall I come under cap exempt now as I can not travel to US with the existing stamping? Is it possible to get the H1B transfer with a new employer in my case? If the case do I need to go for a fresh stamping?
