Short answer

Start with passport, photo, DS-160 confirmation, and fee/appointment records required by your post. Add funds, itinerary, and home-ties evidence that match your real trip. Consistency beats volume.

Core procedural documents

These categories commonly appear in official visitor-visa guidance. Forms, fees, and appointment steps follow your consular post or designated service provider.

  • Valid passport and prior passports if available.
  • Photo that meets current specifications.
  • DS-160 confirmation page.
  • Visa fee payment and interview/drop-box appointment proof as required locally.

Purpose-of-trip supporting evidence

  • Tourism: outline itinerary and transport/lodging plans (watch refundable options).
  • Family visit: relationship and visit plan notes (invitation letters are often not mandatory).
  • Business: meeting invites or company letters aligned with B-1 activities.
The Department of State notes that invitation letters or affidavits of support are generally not required deciding factors. An invitation is not a promise of approval.

Funds and who pays

Be ready to explain how the trip is funded. Bank and employment evidence should reflect reality—avoid unexplained last-minute large deposits.

Home-country ties and identity context

Visitor cases often examine whether the trip is temporary. Work, study, family, or property evidence may help show ties—but there is no universal “approval package.”

Keep DS-160, interview, and documents aligned

  • DS-160 answers should match passport data, itinerary, and spoken answers.
  • Supporting files should reinforce—not contradict—the form.
  • More documents are not always better; irrelevant or exaggerated files can dilute your case.

FAQ

Can I apply without an invitation letter?

Yes. Invitations are often not mandatory for B1/B2. Focus on a credible trip story and consistent evidence that you will depart after a short visit.

How much bank balance is enough?

There is no single threshold for everyone. Funds should fit trip length, cost bearer, and income—and look genuine.

If documents are complete, is approval certain?

No. Documents are only part of the case; the government decides. Do not buy non-refundable travel before approval.

Does the free tier include a full document diagnosis?

Free self-checks and public checklists help you start. Full document review and formal templates are part of paid application assistance—see product pages.
