You’re two weeks from an application deadline, or three days from an embassy appointment, and you need to know one thing. How fast can this actually get done? Here’s a realistic breakdown, not a marketing number.

Standard delivery: 24 to 48 hours

For most single documents, a diploma, a transcript, a birth certificate, a short contract, a properly staffed agency should be able to deliver a certified translation within 24 to 48 hours. This window covers the actual translation, plus a second reviewer checking it before it’s stamped and sealed. If an agency promises certified translation “same day” for a technical or legal document with no mention of a review step, that’s usually a sign the quality check is being skipped, not that they’ve found a shortcut.

Express track: under 12 hours

For genuinely urgent situations, a visa interview tomorrow morning, a court filing due today, a serious agency should offer an express option with a clear, specific turnaround, not a vague “we’ll try.” At Ngaija, our express track delivers certified translations in under 12 hours, without skipping the dual-verification step. It just means the document goes to the front of the queue and both translator and reviewer prioritize it immediately.

What actually slows a translation down

A few things push a delivery time past what you’d expect, and it’s worth knowing them so you can plan around them.

Document length and technicality. A one-page birth certificate and a forty-page set of corporate bylaws are not the same job. Legal and technical documents take longer because the reviewer has to check terminology as carefully as grammar.

Handwriting and scan quality. If the original document is handwritten, faded, or photographed at an angle, the translator has to spend time deciphering it before translating a single word. A clean, high-resolution scan or PDF genuinely saves hours.

Multiple documents in one batch. If you’re submitting a full admissions dossier, transcripts, diploma, recommendation letters, ID, ask upfront whether the delivery time quoted is per document or for the whole batch. This is one of the most common sources of confusion.

Language pair. Common pairs (English to French, English to Spanish) generally move faster simply because more qualified linguists are available. Less common pairs may take longer to staff, even with an express request.

How to make sure you don’t miss a deadline

1. Send your documents as early as possible, even in draft form, so the agency can flag anything unusual (a language pair they need to staff, a technical field that needs a specialist) before it becomes urgent.
2. Ask for a fixed delivery time in writing, not a range. “24 to 48 hours” for a single standard document should become a specific commitment once the agency has actually seen the document.
3. Confirm whether you need one document or a full set. See our guide on the documents typically required for international admissions if you’re not sure what your target university will ask for.
4. Say the deadline out loud. Agencies can’t prioritize what they don’t know is urgent. Always mention your actual deadline, not just “as soon as possible.”
