For those who applied in Taipei, on the website it says application to include 2 inches passport photo. I don't really understand that dimension. Is it asking for a 2x2 inch photo? But on most application forms I see it requesting 4cm x 6cm. Just want to clarify what passport photo dimension the Taipei embassy is asking for
TLDR : Answer Summary
The Taipei embassy requires a passport photo of dimensions 2 inches, which typically refers to a 2x2 inch photo. However, another user confirmed that a 4cm x 6cm photo is also acceptable, based on their recent experience with a specialized photographer.
