Two ways in, one piece of work
Indian receiving offices take documents in by two quite different routes. One is a counter, where paper is handed over, stamped as received and put in a folder. The other is an online form, which has opinions about file types, file sizes and how many attachments it will tolerate. The translation is identical for both; everything that differs happens after it is written, in how the pages are packed.
The language India requires
A certified translation in Leicester for India has to produce English, because English is what a document used in India is expected to be readable in. The source document is unaffected by any of this and keeps its own language and layout. The English is written to travel beside it, which is the reason the two are worth keeping physically or digitally joined.
What makes the set credible
The dated certificate of accuracy signed by a professional certified translator is what turns three loose pages into something an office can act on. It names the document and states that the English matches it. Detach it and the English becomes an unattributed text; keep it attached, in print or in a single file, and the reader has a person and a date to work from.
Per-page cost and turnaround
Pricing is £25 a page with 2–3 business days as standard and 24 hours available on the express route. Deciding early how the set will reach its reader is worth doing, not because it changes the rate, but because it decides whether you need a folder that survives the post or a file small enough for a form to accept without complaint.
