Tips to avoid delays

Keep digital copies (PDF or clear photos) of every document ready before you start.
Make sure names and addresses match exactly across all documents — mismatches are the single most common cause of rejection.
Use current, unexpired government-issued IDs, and have both originals and self-attested copies on hand.
