This Labor Condition Application (LCA) was filed by Day Zero Diagnostics Inc. for the position of Machine Learning Research Scientist in Boston, Massachusetts. The offered annual salary is $120k, compared to the prevailing wage of $101k for this occupation and location. This represents a wage premium of +18.9% above the prevailing wage.
The LCA is the first step in the H-1B visa process. Employers must file an LCA with the Department of Labor certifying that they will pay the foreign worker at least the prevailing wage for the occupation in the area of intended employment. A certified LCA is required before the employer can file an H-1B petition with USCIS.
Case status: Certified - Withdrawn. This means the employer or their representative withdrew the application.
A Labor Condition Application (LCA) is a mandatory document that U.S. employers must file with the U.S. Department of Labor (DOL) before they can petition for a foreign worker under the H-1B, H-1B1, or E-3 visa categories. The LCA process was established under the Immigration and Nationality Act (INA) to protect both foreign and domestic workers by ensuring fair wages and working conditions.
When a U.S. company identifies a foreign national to fill a specialty occupation position, they must first obtain DOL certification through the LCA process before filing the H-1B petition (Form I-129) with U.S. Citizenship and Immigration Services (USCIS). In this case, Day Zero Diagnostics Inc. filed LCA case number I-200-21112-248543 to sponsor a Machine Learning Research Scientist position at their worksite in Boston, Massachusetts. By filing this LCA, the employer attests to four key conditions: (1) paying the higher of the actual wage or prevailing wage, (2) providing working conditions that will not adversely affect other similarly employed workers, (3) no strike or lockout at the worksite, and (4) providing notice of the filing to the bargaining representative or posting notice at the worksite.
The DOL establishes four wage levels for each occupation and geographic area, representing the progression from entry-level to fully competent workers:
For this filing, the offered wage of $120k compares to the DOL prevailing wage of $101k for Biostatisticians positions in the Boston, Massachusetts area. The positive wage premium of +18.9% indicates the employer is offering above the DOL-determined average for this occupation and location.
The prevailing wage is the average wage paid to similarly employed workers in a specific occupation in the area of intended employment. The DOL determines prevailing wages using data from the Occupational Employment and Wage Statistics (OEWS) survey conducted by the Bureau of Labor Statistics (BLS). Employers must pay H-1B workers the higher of the prevailing wage or the actual wage paid to other employees in similar positions at the company. This requirement is designed to prevent employers from using H-1B workers to undercut domestic wages.
A "Certified-Withdrawn" status means this LCA was initially certified by the DOL but was later withdrawn by the employer. This can happen for various reasons: the foreign worker may have declined the position, found employment elsewhere, the employer may have decided to refile with updated information, or business conditions may have changed. A withdrawal does not negatively affect the employer's ability to file future LCAs.
This LCA was received by the DOL on Apr 22, 2021 and a decision was rendered on Feb 21, 2024, a processing time of approximately 1035 business days. The standard DOL processing time for LCA applications is 7 to 10 business days. This application took longer than the standard timeframe, which may indicate additional review was required.
The offered salary of $120k for this Machine Learning Research Scientist position provides a data point for evaluating compensation trends in H-1B visa sponsorship. When reviewing H-1B salary data, consider that wages vary significantly based on geographic location, employer size, industry sector, and the worker's experience level. This position falls under SOC code 15-204101 (Biostatisticians), which standardizes how the Bureau of Labor Statistics classifies occupations across industries. Metropolitan areas like New York, San Francisco, and Seattle typically command higher salaries due to higher costs of living, while positions in smaller markets may offer lower nominal wages but comparable purchasing power.
The offered annual salary for this Machine Learning Research Scientist position at Day Zero Diagnostics Inc. is $120k. The Department of Labor prevailing wage for this occupation and location is $101k. The offered wage represents a +18.9% premium over the prevailing wage.
