So just to summarize,The translations will go with along with the documents in the place provided, and so will the PoF, affidavits etc.
Only the LoE should be in the separate placeholder and keep it short.
1. Same name affidavits for both myself and spouse - attach in LOE section
2. Affidavits from spouse for POF use - attach in POF section
3. Affidavits for translations - in the Marriage Certificate section
Is this correct? Thank you for the support and sorry for all the trouble.
