The US Supreme Court has overturned a 40-year-old precedent, allowing courts to independently review federal agency decisions. This could benefit US employers challenging unfavorable USCIS decisions on H-1B visa extensions but may lead to new litigation over H-4 visa work authorizations. Immigration attorneys highlight mixed implications: it may help employers contest strict visa interpretations, yet H-4 visa holders face uncertainty. The Loper Bright decision removes automatic deference to agency interpretations, impacting how immigration laws are applied.
