You can find interview wait times on the travel.state.gov website here: https://travel.state.gov/content/travel/en/us-visas/visa-information-resources/wait-times.html. The wait times often include those for third country nationals (TCNs), but the site does not specify if there are separate queues for TCNs at individual posts. Additionally, due to technical constraints, the Department of State has noted that providing TCN-specific wait times is currently not feasible.
