A US court has dismissed a lawsuit that challenged the lottery system for determining successful applicants for H-1B visas, the most sought after by Indian IT firms and professionals. The ruling by a federal judge in Oregon means that there will be no change in the H-1B visa issuance process for the fiscal 2018 which begins on April 3.<br/><br/>As a result, successful H-1B visa applicants are expected to be determined by the US Citizenship and Immigration Services (USCIS) through a lottery system. The case against the lottery system was filed by two firms from Portland. <br/><br/>The USCIS resorts to a computerised draw of lots if the number of H-1B visa applications crosses the Congressional allotted quota in the first five days after it starts accepting the petitions every year in the month of April.
