According to the new proposal, United States prohibits employers from filing multiple H-1B visa applications for the same employee.
In a statement issued, the US Citizenship and Immigration Services said "To ensure a fair and orderly distribution of available H-1B visas, USCIS will deny or revoke multiple petitions filed by an employer for the same H-1B worker and will not refund the filing fees submitted with multiple or duplicative petitions".
These changes are expected to ensure a fair and orderly distribution of available visas.
