Crop your OCI card photo. Same size as an India passport photo, different background.

An Overseas Citizen of India (OCI) card photo is the same physical size as an India passport photo: 2x2in (51x51mm), with your head measured chin-to-crown between 1 and 1⅜ inches (25 to 35mm). Where the two specs diverge is the background: the OCI photo needs a plain, light background that is not pure white, while the passport photo requires plain white. Reusing an existing passport photo as-is for an OCI application is one of the more common reasons a photo gets rejected.

Digital uploads for the OCI application are roughly 200x200 to 900x900 pixels, JPEG format, under 200KB. The tool above exports at 600x600px, comfortably inside that range.

The exact digital pixel and file-size figures here are cross-checked against third-party sources rather than an independently re-parsed primary PDF. Always confirm current requirements against the official OCI Services portal before submitting.

OCI stands for Overseas Citizen of India. It's a lifelong document the Indian government issues to people of Indian origin who now hold a foreign passport, and to the foreign spouses of Indian citizens or existing OCI holders. In practice, an OCI card works like a permanent, multiple-entry visa: it's stapled into your foreign passport and lets you enter and stay in India without applying for a fresh visa every time. It doesn't make you an Indian citizen again, and it isn't a substitute for your actual passport, the two travel together.

You'll sometimes see this confused with a PIO (Person of Indian Origin) card. That's an older, separate scheme that the government discontinued in 2015 and folded into OCI. If you're applying today, or if you still hold an old PIO card and need to convert it, you're going through the same OCI application process, and the photo requirement on this page applies either way.

OCI applications are filed online through the OCI Services portal at ociservices.gov.in. You fill in the form, upload supporting documents, and attach your photo before paying the fee and printing the acknowledgement. That acknowledgement, along with your original documents, then goes to your nearest FRRO office if you're applying from within India, or to the Indian embassy or consulate handling OCI cases if you're applying from abroad.

The photo isn't just filed once and forgotten. If you later come back for an OCI miscellaneous services request, say, a reissue after getting a new passport, updating your particulars, or replacing a lost card, you'll be asked to upload a fresh photo that meets this same 2x2in, plain light background spec. There's no separate, looser standard for these follow-up requests.

Beyond the size itself, most of the documents you'll be asked for have nothing to do with the photo: your current foreign passport, proof of Indian origin (an old Indian passport, or a parent's or grandparent's Indian passport or birth certificate), proof of your current foreign citizenship, and a marriage certificate if you're applying as a spouse. The checklist shifts slightly by category, so it's worth confirming the current list on the portal before you start, but the photo spec on this page stays constant across all of them.

Getting the pixel dimensions right only clears the automated upload check on the portal. Most real rejections happen at manual review, and they're rarely about size. The single most common mistake is background colour: applicants reuse a passport photo, which is meant to be pure white, on an OCI form that specifically wants a plain, light, off-white or pale-toned background instead. It's a small distinction, and it's the exact opposite of what a lot of people assume.

After background, the usual culprits are tinted or photochromic glasses, glare across the lenses, visible shadows on the face or backdrop, and photos that look noticeably filtered, smoothed, or touched up. None of that trips an automated size check, it only shows up once a person reviews the file. Uploading a photo that's already correctly cropped and on the right background from the start, rather than trying to fix a rejected one after the fact, is the more reliable way through.

An OCI card's main practical benefit is that multiple-entry, lifelong travel to India, without registering with local police for long stays, which is otherwise required of most foreign nationals staying beyond a set period. Cardholders also get broad economic and educational parity with Non-Resident Indians (NRIs), covering things like domestic airfares, entry fees at national monuments, and most banking and investment rules. A handful of restrictions remain, mainly around buying agricultural land, certain government or constitutional posts, and voting rights, none of which the OCI card grants.

OCI holders who spend enough time in India (182 days or more in the year before applying) can also apply for an Aadhaar number through the regular UIDAI process, separate from the OCI application itself. The card doesn't have a fixed expiry or renewal cycle, but it does need to be re-issued when your passport is renewed before you turn 20 and again after you turn 50, since the OCI record is tied to your current passport details.

It's also worth being clear about what OCI status is not: it's a residency and travel status, not citizenship, and not the same thing as being an NRI. An NRI is an Indian citizen living abroad and still holds an Indian passport, while an OCI holder has given up Indian citizenship and travels on a foreign one. The two aren't interchangeable, and you can't hold NRI status and OCI status at the same time.
