USCIS issues an EAD card for unrestricted employment in the USA. The EAD card is also known as form I-766. The application form for an EAD card is called form I-765. Form I765 requires an EAD category code to approve your eligibility.

2023年9月6日 · If you are not a citizen or a lawful permanent resident, you may need to prove that you can work in the United States by presenting an Employment Authorization Document (Form I-766/EAD). You may apply for an EAD if you are eligible.

2012年6月11日 · Using the EAD with Air Dive Tables In nitrox dive planning, the EAD information (once determined) is simply applied to a standard set of air dive tables; the tables plot the dose of nitrogen experienced by the diver, based upon depth and time.

Agencies verifying eligibility of applicants for benefits are frequently presented with an I-766 Employment Authorization Document (EAD). To assist agencies in determining the applicant’s eligibility, the following chart contains many of the EAD category codes and the provisions of the federal regulations to which they refer.

2024年12月16日 · This article will provide details on the Employment Authorization Document(EAD) Category Codes, the complete list of the codes, and what categories are eligible for the 540-day automatic extension.

This concept is known as equivalent air depth (abbreviated as EAD). To demonstrate the concept of equivalent air depth, consider Table 7 (below), which depicts the partial pressure of nitrogen in air, as well as in the mixes of EAN32 and EAN40, at various depths.

The equivalent air depth (EAD) is calculated using the formula: FN 2 EAD=(FN2 *(d+x))-x 0.79 Another Form of the equation can be shown as EAD = FN 2 * (d + x) - x 0.79 FN 2 is the fraction of nitrogen in the nitrox mix 0.79 is the fraction of nitrogen in air (including the trace gases) d is the actual depth in the appropriate units (fsw or msw)

The equivalent air depth (EAD) is a way of approximating the decompression requirements of breathing gas mixtures that contain nitrogen and oxygen in different proportions to those in air, known as nitrox.

This document provides information on Employment Authorization Document (EAD) category codes that are found on EAD cards. It includes a chart with the EAD codes, definitions of who falls under each code based on their alien status, and the corresponding regulations.

Plastic Equivalent Air Depths Table. This chart allows you to quickly calculate what percentage of your total oxygen exposure limits you have consumed on each dive. Time values in this chart are based on the NOAA Oxygen Exposure Time Limits for Working Divers.
