The H1B petition process unfolds annually from March to October, beginning with a two-week registration period in March, culminating in lottery results released by the month's end. Following this, from April 1st to June 30th, a certified U.S. visa attorney submits the H1B petition, accompanied by all necessary documentation. Between July 1st and September 30th, applicants await the petition results, though delays beyond September occasionally occur. Upon receiving the Approval Notice, candidates proceed with visa stamping. Only after October 1st can they officially begin job applications within the United States. This structured timeline ensures a systematic approach to securing H1B visas each year, guided by legal expertise and regulatory compliance.
