s/H1B/LCA
I'm in that data, yet I have an E-3, not an H-1B.
One unintended consequence of moving to the US that I wasn't expecting is that now my friends back home roughly know what my salary is. I understood when moving here that the LCA (which has salary details) would be posted in public spaces, but I didn't notice it was also a matter of public record which in this day and age, means global public record.
I work in a smaller city, so while I may have been relatively anonymous in somewhere like Silicon Valley, my location, company and role and year of employment is more that enough to uniquely identify me. Such is life.
