While I directionally agree with the conclusion, O-Net is not a good source for relevant occupational and task classifications.

While it is continuously updated, it lacks many modern white-collar occupations, such as occupations in finance, tech, or consulting. And when it does carry an occupation, it often misses the mark on the relevant task set.

Every immigration attorney who had to build labor certs around O-Net can confirm how frustrating and backwards the database is. Just imagine trying to justify an H1-B for, say, a sales & trading associate at an investment bank when the only available options are bank teller, financial analyst, risk examiner, and 2-3 other ill-fitting categories.

That being said, occupational classification is an impossible task for a variety of reasons..
