United States Department of Labor in the context of "Occupational Information Network"

Science, technology, engineering, and mathematics (STEM) is an umbrella term used to group together the related technical disciplines of science, technology, engineering, and mathematics. It represents a broad and interconnected set of fields that are crucial for innovation and technological advancement. These disciplines are often grouped together because they share a common emphasis on critical thinking, problem-solving, and analytical skills. The term is typically used in the context of education policy or curriculum choices in schools. It has implications for workforce development, national security concerns (as a shortage of STEM-educated citizens can reduce effectiveness in this area), and immigration policy, with regard to admitting foreign students and tech workers.

There is no universal agreement on which disciplines are included in STEM; in particular, whether or not the science in STEM includes social sciences, such as psychology, sociology, economics, and political science. In the United States, these are typically included by the National Science Foundation (NSF), the Department of Labor's O*Net online database for job seekers, and the Department of Homeland Security. In the United Kingdom, the social sciences are categorized separately and are instead grouped with humanities and arts to form another counterpart acronym HASS (humanities, arts, and social sciences), rebranded in 2020 as SHAPE (social sciences, humanities and the arts for people and the economy). Some sources also use HEAL (health, education, administration, and literacy) as the counterpart of STEM.

The United States secretary of commerce (SecCom) is the head of the United States Department of Commerce. The secretary serves as the principal advisor to the president of the United States on all matters relating to commerce. The secretary reports directly to the president and is a statutory member of the Cabinet of the United States. The secretary is appointed by the president, with the advice and consent of the United States Senate. The secretary of commerce is responsible for promoting American businesses and industries. The department states its mission as 'to foster, promote, and develop the foreign and domestic commerce of the United States'.

Until 1913, there was one secretary of commerce and labor, uniting this department with the United States Department of Labor, which is now headed by a separate United States secretary of labor.

The Occupational Safety and Health Administration (OSHA; /ˈoʊʃə/) is a regulatory agency of the United States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. The United States Congress established the agency under the Occupational Safety and Health Act (OSH Act), which President Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance". The agency is also charged with enforcing a variety of whistleblower statutes and regulations. OSHA's workplace safety inspections have been shown to reduce injury rates and injury costs without adverse effects on employment, sales, credit ratings, or firm survival.

Priority date is a United States immigration concept – it is the date when a principal applicant first reveals his or her intent of immigration to the US government. For family-sponsored applicants, the priority date is the date an immigration petition, filed on behalf of him or her, is received by the United States Citizenship and Immigration Services (USCIS). For employment-based immigration beneficiaries, the priority date is the date an immigration petition is filed at USCIS, under categories where a labor certification is not required, or when the United States Department of Labor receives a labor certification application, under categories where a labor certification is required. In all cases, the priority dates are not established until USCIS approves the immigration petition. The date establishes one's place in the queue for a family-sponsored or employment-based or permanent residency permit (also known as "green card") application.

The United States Department of State publishes a monthly Visa Bulletin which lists cut-off dates for different immigration categories and countries of birth. Only those intending applicants with priority dates before the cut-off date are permitted to file their Adjustment of Status (AOS) applications or attend immigrant visa interviews at consulates. The cut-off dates generally move forward over time as old cases are approved or abandoned. However, in certain cases, such as if a large number of old cases work their way through the system at about the same time, the cut-off dates can actually retrogress (or roll back). If an individual already has a pending AOS application on file when a retrogression occurs that places the cut-off earlier than the applicant's priority date, USCIS sets the application aside and will not adjudicate it until the priority date is current again. As an example, after months of stagnation, in June 2007 the priority date cut-offs for employment-based second and third-preference (EB2 and EB3) applicants (the bulk of employment-based green card applicants) advanced dramatically for all countries of birth. On the low end, the cut-off advanced eight months for immigrants from mainland China for EB2 category. EB3 for India-born applicants has moved forward 25 months, the most of any category, thus impacting a huge number of workers with jobs requiring bachelor's degrees.

The US Employment Service (ES) is the national system of public employment offices, managed by state workforce agencies and their localities, and funded by the Department of Labor. It is supervised by the Employment and Training Administration and was established by the Wagner–Peyser Act of 1933.

Crystal City is an urban neighborhood in the southeastern corner of Arlington County, Virginia, approximately 5 miles (8.0 km) south of Downtown Washington, D.C. Due to its extensive integration of office buildings and residential high-rise buildings using underground corridors, travel between stores, offices, and residences, it is possible to travel much of the neighborhood without going above ground, making part of Crystal City an underground city.

Crystal City includes several aerospace manufacturing and defense industry companies, public sector consulting firms, government contractors, the U.S. Department of Labor, the U.S. Marshals Service, satellite offices for the Pentagon, and nonprofit organizations, including the International Foundation for Electoral Systems and the national headquarters for PBS.

A flammable liquid is a liquid which can be easily ignited in air at ambient temperatures, i.e. it has a flash point at or below nominal threshold temperatures defined by a number of national and international standards organisations.

The Occupational Safety and Health Administration (OSHA) of the United States Department of Labor defines a liquid as flammable if it has a flash point at or below 93 °C (199.4 °F). Prior to bringing regulations in line with the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in 2012, OSHA considered flammable liquids to be those with a flash point below 37.8 °C (100.0 °F). Those with flash points above 37.8 °C/100 °F and below 93.3 °C (199.9 °F) were classified as combustible liquids. Studies show that the actual measure of a liquid's flammability, its flash point, is dependent on the local air pressure, meaning that at higher altitudes where the air pressure is lower, the flash point is also lower.

The Bureau of Labor Statistics (BLS) is a unit of the United States Department of Labor. It is the principal fact-finding agency for the U.S. government in the broad field of labor economics and statistics and serves as a principal agency of the U.S. Federal Statistical System. The BLS collects, processes, analyzes, and disseminates essential statistical data to the American public, the U.S. Congress, other Federal agencies, state and local governments, businesses, and labor representatives. The BLS also serves as a statistical resource to the United States Department of Labor, and conducts research measuring the income levels families need to maintain a satisfactory quality of life.

BLS data must satisfy a number of criteria, including relevance to current social and economic issues, timeliness in reflecting today's rapidly changing economic conditions, accuracy and consistently high statistical quality, impartiality in both subject matter and presentation, and accessibility to all. To avoid the appearance of partiality, the dates of major data releases are scheduled more than a year in advance, in coordination with the Office of Management and Budget.
