Why This Number Matters

Total sponsorship volume is the figure most job boards quote, and on its own it is misleading. An employer filing thousands of petitions a year can be filing almost all of them to extend people it sponsored years ago, which tells an outside applicant very little about their odds.

The new-employment share separates the two. It is the employer's own checkbox on the Labor Condition Application, not an estimate, and it identifies the filings that represent someone entering the company rather than staying in it.
