What language will be used?
Participants should be comfortable engaging in English. Final language arrangements should be confirmed in onboarding materials.
Is the proposed C2C LAB experience guaranteed?
It should only be presented as confirmed after written operational approval. Until then, retain the “proposed” wording.
Will I receive a C2C certificate?
The experience is being structured to include a C2C Certificate of Participation, subject to final written confirmation, approved wording, and completion of the applicable attendance requirements.
Can IW guarantee my visa or entry into Germany?
