TL;DR
The DS-160 is the online US nonimmigrant visa application form, and it comes first. One per applicant, children included. Sign and submit it at least 2 business days before your interview and print the confirmation page. Its number must match the number in your appointment account or you will be turned away at the door. If you find an error after submitting, complete a new DS-160.
What the DS-160 is, and where it sits
The embassy's nonimmigrant visa page sets out three steps: complete the DS-160 and print the confirmation page, pay the visa fee and schedule an interview at ais.usvisa-info.com/en-gb, then attend with your documents. The DS-160 is step one, and nothing else can start until it is done.
Each applicant completes their own form. A family of four needs four DS-160s and four confirmation pages, and a child's form is not optional.
The confirmation page is the document that matters
What you carry to the interview is the printed confirmation page, not the whole application. Print one for every applicant. If you leave it at home, the interview does not happen.
The 2 business day rule, and the matching number
Two hard rules sit around the DS-160, and both are checked before you reach an officer.
- The form must be signed and submitted at least 2 business days before the appointment.
- The DS-160 number must match the number held in your appointment account on the official scheduling site.
If either fails, you are refused entry to the building and the appointment has to be rebooked. Visa fees are non-refundable and non-transferable, so a mismatch is an expensive way to lose a morning. We recommend opening the scheduling account and the confirmation page side by side and reading the number twice, the day before you travel. Our guide to booking the appointment in London covers the booking side of the same check.
The social media identifiers question
The DS-160 asks every applicant for social media identifiers. The embassy's nonimmigrant visa page says to ensure all social media accounts are listed on the DS-160 and set to public, and its visas page names the classes told to set accounts to public: F, M, J, H-1B and others.
Answer it accurately. List the accounts you genuinely use, under the handles you genuinely use. We recommend doing this calmly and early rather than at the end of a long session, because it is the field people rush.
The photograph
You bring one physical colour photograph to the interview: 5 x 5 cm, or 2 x 2 inches, on a white background, taken within the last six months, not digitally edited and with no AI-generated content. A photograph that fails the requirements can mean being refused entry to the building and a new appointment. Get it taken properly rather than cropped from a phone picture.
Mistakes we see most often
These are our observations from preparing applications, not official rules. They are still the things that cost people the most time.
- Dates that do not agree with each other. Employment dates, travel dates and dates on your supporting documents should tell one story. In our experience, an officer who finds one date that does not fit starts checking the rest.
- Leaving previous travel out. Earlier trips, including trips to the United States, belong on the form. So does anything you would rather not mention.
- Leaving a previous refusal out. A past refusal is not a reason to hide it. Evidence of previously issued US visas is on the embassy's document list, and our page on 214(b) refusals explains how a reapplication is meant to work.
- Passport details that do not match the passport. Names, spellings, passport number and dates of birth must be copied character for character. This is the single most common cause of a mismatch.
- One form for a family. Each applicant needs their own.
If you notice an error after submitting
Complete a new DS-160. Submit it, print the new confirmation page, and then check that the new number matches the number in your appointment account before you travel. Do not rely on carrying the old page and explaining at the door.
What to do next
Once the form is submitted, the rest is the pack and the interview. Start with the pillar guide to the US visitor visa from the UK, then the document list for UK residents and the London interview guide. The Bundler assembles your file in the right order and the Compressor sizes it. When you are ready, the plan step tells you where you stand.

Common questions
- 01
What is the DS-160 and who has to complete one?
The DS-160 is the online application form for a US nonimmigrant visa, including the B1/B2 visitor visa. Every applicant completes their own, including children, and prints their own confirmation page. It is the first of the three steps the embassy sets out, before you pay the visa fee or schedule an interview on the official site.
- 02
How far in advance must the DS-160 be submitted?
The DS-160 must be signed and submitted at least 2 business days before your interview appointment. The number on the confirmation page must also match the number held in your appointment account. If either of those is wrong on the day, you are refused entry to the building and the appointment has to be rebooked.
- 03
Does the DS-160 ask about social media?
Yes. The DS-160 asks every applicant for social media identifiers. The embassy's nonimmigrant visa page says to ensure all social media accounts are listed on the DS-160 and set to public, and its visas page names the classes told to set accounts to public: F, M, J, H-1B and others. List the accounts you actually use, accurately.
- 04
What photo do I need for the DS-160 and the interview?
You bring one physical colour photograph, 5 x 5 cm or 2 x 2 inches, on a white background, taken within the last six months, not digitally edited and with no AI-generated content. The embassy is strict about this: a photo that fails the requirements can mean being refused entry to the building and needing a new appointment.
- 05
What if I made a mistake on my submitted DS-160?
You will need a new DS-160. Complete a fresh form with the correct details, submit it, print the new confirmation page, and make sure the new number matches the number held in your appointment account on the official scheduling site. Check the match before you travel to the interview, because the door staff check it rather than the officer.
