Immigration and applicant tracking system

IIATS is the operating system for a recruitment business that places skilled workers from non-EU countries into German employers. It covers the full lifecycle: sourcing, language school, visa segment, authority filing, placement, and invoicing.
Three self-service portals sit on top of the same data — one for candidates, one for employers, and one for language schools — so each party sees their slice of the pipeline without anyone emailing a spreadsheet around.
Immigration recruitment is a compliance workflow disguised as a sales pipeline. A candidate's route depends on their visa segment, and the segment decides which German state authority handles the filing, which decides the documents, the timeline, and the failure modes.
Run by hand, that means a coordinator holding rules in their head across dozens of candidates. Cases stall silently, documents expire unnoticed, and nobody finds out until an authority rejects a filing.
