E-3 Visa is a special U.S. work visa for Australian nationals.
Previously, the premium processing option was not available for E-3 petitions. This meant that, unlike the general U.S. work visa, the H-1B Visa, there was no option of paying premium processing fee and receiving a quick decision on an E-3 petition within 15 days of filing the petition.
However, starting from February 24, 2021, premium processing became available for E-3 petitions, which means that the petitioners of E-3 will have an option of paying $2,500 of premium processing fee to the USCIS and receiving the decisions (either approval or request for further information) within 15 days of filing their petition.
