According to the March 15, 2017, UCSIS press release, April 3, 2017, is the first day to file for your H-1B visa.
As you know, the H-1B visa program is beneficial for United States companies. This visa permits employers to temporarily (up to 3 years) employ foreign workers in work requiring highly specialized knowledge and a bachelor’s (or equivalent) degree or higher (in that area of knowledge). Generally, these fields of work include science, engineering and information technology.
While Congress has set a 65,000 H-1B visa cap each fiscal year, there is an exception for up to 20,000 beneficiaries who have earned a U.S. master’s degree or higher. USCIS has also announced that as of April 3, 2017, they will be suspending premium processing for all H-1B petitions. This suspension may last up to six months. Note also that the Form I-129 filing fee increased to $460 and if your check is dishonored, the USCIS will reject the entire application without the option to correct it.
