OCI photo and signature requirements

A square photo and a 3:1 signature, each under 500 KB: what the OCI portal checks and how to get both right.

Updated 9 October 2026

The OCI (Overseas Citizen of India) online application asks you to upload a photo and a signature. According to Indian missions, photos and signatures that don't meet the rules are among the most common reasons OCI applications are sent back.

Photo requirements

RuleRequirement
ShapeSquare (1:1)
SizeFrom 200 × 200 to 1500 × 1500 pixels
FileJPG or JPEG, up to 500 KB
Printed photoAt least 51 × 51 mm (2 × 2 inch)
FaceAbout 80% of the frame, centred
BackgroundPlain and light-coloured, with no border

The OCI photo maker creates a 600 × 600 JPEG under 500 KB. Drag and zoom so your face fills most of the square.

Signature requirements

RuleRequirement
Shape3 times as wide as it is tall (3:1)
SizeFrom 200 × 67 to 1500 × 500 pixels
FileJPG or JPEG, up to 500 KB
InkBlue or black, inside the signature box

Sign on plain white paper, take a photo of it, then open the signature maker, choose Upload photo and the size 600 × 200 px, and download the JPG. The signature must match the one on your printed form and in your passport.

Common reasons for rejection

Each Indian embassy or consulate publishes its own OCI instructions, and some add rules for the printed photos. Check the page of the mission handling your application.
