How to Apply for a US Visa: Step-by-Step Guide

Applying for a US visa follows the same three-stage process everywhere, regardless of why you’re traveling — tourism, business, study, or crew duty: complete the DS-160 form, pay the $185 MRV fee and schedule an interview through your consulate’s booking system, then attend an in-person interview at the US embassy or consulate serving your country. In Turkey specifically, that’s the US Embassy in Ankara or the US Consulate General in Istanbul, booked through USTravelDocs — and according to official FY2025 figures, roughly 22.25% of nonimmigrant visa applications from Turkey were refused, a reminder that the process rewards a consistent, well-prepared file far more than a thick stack of documents, wherever you’re applying from.

Quick Facts

• Application form: DS-160, completed for free at ceac.state.gov — the same for every country
• Appointment system: varies by country — in Turkey, USTravelDocs (the older AIS system was fully retired there; some other countries, like Italy and Germany, still use AIS)
• Application fee: $185 per person everywhere; how you pay varies by country — in Turkey, Mastercard online or cash at Garanti BBVA
• Interview requirement: mandatory for every applicant since a 2025 update, regardless of age
• Document delivery: varies by country — in Turkey, handled by VFS Global and UPS (PTT, the national postal service, is no longer used)
• Result: communicated verbally at the end of the interview
• Typical delivery time: in Turkey, your passport reaches you in about 10 days after your visa is printed

Step 1: Complete the DS-160 Form

Every nonimmigrant application — whether for a short visit, a degree program, or crew duty — starts with the DS-160, Online Nonimmigrant Visa Application. The form must be completed in English, and every answer needs to be accurate and consistent with the documents you’ll eventually bring to your interview.

As you fill it out, note the Application ID the system assigns you, and once you submit it, save and print the barcoded DS-160 confirmation page — you’ll need the confirmation number to book your appointment in the next step. A form completed with contradictory or incomplete answers is one of the most common causes of delay and refusal, so it’s worth taking real time over it rather than rushing through in one sitting.

You can access the official form here: DS-160 Online Application (CEAC).

Step 2: Pay the Visa Fee and Book Your Interview

Once your DS-160 is submitted, create an account on your consulate’s official appointment system. In Turkey, that’s USTravelDocs, which fully replaced the older AIS platform there — other countries may still use AIS or their own system, so confirm which one applies where you’re applying. Through this account you’ll pay the $185 MRV fee — in Turkey, online payment accepts Mastercard-branded cards only, or you can pay in cash at a designated Garanti BBVA branch — and then select an interview date.

In Turkey specifically, appointments are available at two posts:

• US Embassy, Ankara — 1480 Sokak No. 1, Çukurambar Mahallesi, 06530 Çankaya, Ankara
• US Consulate General, Istanbul — Poligon Mahallesi, Sarıyer Caddesi No. 75, İstinye, 34460 Sarıyer, Istanbul

You may book at either post regardless of which city you live in, and appointment availability at each can differ substantially depending on the season — it’s worth checking both before committing to a date. Note that you can only interview at the post serving the country where you hold citizenship or legal residence; applicants based in Turkey generally can’t book an interview in a third country. Once your appointment is confirmed, print the Appointment Confirmation letter — you’ll need it to enter the consulate.

Keep your MRV fee receipt and your USTravelDocs account details (including your security questions) somewhere safe; you may need them again if you reschedule or reapply later.

Step 3: Prepare Your Documents

Because the US visa process weighs your stated purpose of travel and your interview more heavily than paperwork volume, there’s no single universal checklist — required documents vary by visa category and personal profile. That said, a small set of items is mandatory for essentially every applicant:

• Your DS-160 confirmation page
• Your USTravelDocs appointment confirmation
• A passport valid for at least 6 months beyond your intended stay
• One recent digital photo (600×600–1200×1200px, square) meeting US visa specifications

Beyond these, supporting evidence — an invitation letter, proof of employment or enrollment, bank statements, or old passports showing prior travel — is presented only if the consular officer asks for it, and what actually strengthens a file depends heavily on the visa category and the applicant’s situation. If you’re applying for a specific category, our dedicated guides go into the documents that matter most for that path:

• F1 Student Visa: Complete Guide
• C1/D Crew Visa: Complete Guide
• J1 Exchange Visitor Visa: Complete Guide

Step 4: Attend Your Consulate Interview

Arrive at the consulate roughly 15–30 minutes before your scheduled time. Security rules are strict — large bags and electronics, including phones, generally aren’t allowed inside, so plan to leave them with someone waiting outside or in a locked vehicle. At the consulate your documents are checked and your fingerprints are taken before you’re called for your interview itself.

The interview is normally conducted by a consular officer in either Turkish or English and, for most nonimmigrant categories, lasts well under five minutes. The single most common opening question is simply why you’re traveling to the United States — answer it clearly and specifically rather than generically, and make sure everything you say lines up with what you entered on your DS-160. The officer’s real question, underneath whatever they ask, is whether they believe you’ll return home once your authorized stay ends.

At the end of the interview you’re told the result on the spot:

• Approved — your passport is retained for visa printing.
• Administrative Processing — your case needs further review; you may be asked for additional documents, and a decision follows once that review is complete.
• Refused — you receive a letter explaining the basis for refusal (most commonly citing Section 214(b)) along with your passport, the same day.

After Approval: When Will I Get My Passport Back?

Once the consulate confirms approval at your interview, your visa is typically printed within 3 business days, and your passport — with the visa affixed — reaches you in an average of 10 days, delivered through VFS Global or UPS depending on the option you selected. Cases placed into Administrative Processing take longer, sometimes extending to a few weeks, and appointment availability itself shifts fairly often depending on the season, so it’s worth confirming current wait times before finalizing travel plans.

Which Visa Do You Actually Need?

“US visa” covers a wide range of categories built around very different purposes: short visits and business trips (B1/B2), academic study (F1), cultural exchange and work-travel programs (J1), and crew duty aboard commercial ships or aircraft (C1/D), alongside categories this guide doesn’t cover in depth, from investment and specialty-occupation work visas to diplomatic travel. Applying under the wrong category — or under the right category but with a weak, inconsistent file — is one of the most avoidable reasons for refusal.

Get Support With Your Application

A US visa application can be completed entirely on your own, but with roughly one in four applications from Turkey ending in refusal, small mistakes in the DS-160 or an unprepared answer at interview carry a real cost — including making your next application harder.
