It’s by country of birth. So that applicant with the long wait could be from Canada if they were born in India.

Looks like there's a small backlog for Mexico/Philippines, large backlog for China and even larger for India-born employment-based applicants.

see https://travel.state.gov/content/travel/en/legal/visa-law0/v... and click on the latest bulletin. You'll probably want to look at the employment-based green card waiting list.

Note that if the country of birth is not explicity listed, such as Canada, the intending immigrant must use the column "All Chargeability Areas Except Those Listed".

For example, a EB2 applicant born in Canada filing today would be backlogged because the date of filing is listed as 01JAN23.
