This is an annual call open across all disciplines, with applications in languages other than English possible in some humanities and social sciences fields by prior agreement.

## Who should apply

- Researchers based at Swiss institutions (SNSF-eligible) and one of six eligible Belgian universities in Wallonia-Brussels
- Research teams planning genuine international collaboration with synchronized timelines
- Projects in any discipline (humanities, social sciences, natural sciences, engineering eligible)
- Applicants willing to navigate dual submission and coordination with partner agency

## Key dates

- SNSF deadline: 1 October 2026 (copy must be submitted to SNSF within 7 days of F.R.S.-FNRS submission)

## Tips for applicants

- If leading through F.R.S.-FNRS (Belgium), submit to your national agency first, then copy to SNSF within 7 days; coordination between Swiss and Belgian partners is essential to meet both deadlines.
- Belgian applicants must verify their institution is one of the six eligible universities; if outside Wallonia-Brussels or not on the list, you cannot be the Belgian lead.
- Non-English language proposals in humanities and social sciences require written agreement from all agencies before submission; contact SNSF and F.R.S.-FNRS in advance to avoid delays.
