What the DS-160 is and who must file it
22 CFR 41.103(a)(1) provides: “Every alien seeking a nonimmigrant visa must make an electronic application on Form DS-160.” The State Department's DS-160 page states that applicants for all nonimmigrant categories, including K visas, must submit it, and that consular officers use it together with the interview to determine eligibility. A completed DS-160 constitutes the applicant's registration under INA section 221(b).
Each family member travelling together needs a separate DS-160; the system lets you start a family member's application from the “Thank You” page, but each application is individual. For children under 16 or applicants who are physically incapable, 22 CFR 41.103(a)(2) allows a parent or guardian to complete and sign the form.
What to have ready before you start
Take every answer from actual documents: current passport and any old passport with US visas or entry stamps; travel plans and US address; work and education history; parents' and spouse's details; previous US travel and any visa issued or refused; and a digital photo meeting the requirements. F-1 and J-1 applicants need their I-20 or DS-2019 first, because the form asks for information from it.
The State Department's DS-160 page lists Internet Explorer 11 or higher, Firefox and Google Chrome as supported browsers and states that Safari and Microsoft Edge are not supported.
Completing the DS-160 step by step
First, go to the official site ceac.state.gov/genniv, select Thailand (Bangkok or Chiang Mai) as the location, and record the Application ID the system gives you.
Second, answer every section in English. The FAQs state: “All answers must be in English, using English characters only”, except the full name in your native alphabet, which may be entered in Thai script.
Third, save as you go. You can return to a partially completed application within 30 days using the Application ID; after that, save it with “Save Application to File”.
Fourth, upload a digital photo that meets the requirements below.
Fifth, review every answer and sign. Under 22 CFR 41.103(b)(3) the form is signed electronically by clicking “Sign Application” in the certification section, confirming that the statements are made under penalty of perjury.
Sixth, print and keep the barcode page — the DS-160 page says you do not need to print the full application — then pay the fee and book your interview, since the Embassy or Consulate does not schedule it for you.
Having someone help you
The State Department FAQs allow a third party to help an applicant who is illiterate or unable to complete the form. The helper must be listed on the “Sign and Submit” page and must instruct the applicant how to sign; the applicant clicks “Sign Application”.
Visa Connext prepares the answers from the applicant's documents, checks consistency with every document, discloses its role as required by the form, and has the applicant review every answer before signing personally.
DS-160 photo requirements
State Department photo rules: taken within the last 6 months, in colour, against a plain white or off-white background, neutral expression with both eyes open, no eyeglasses (“Eyeglasses are no longer allowed in new visa photos”), and no hat or head covering that obscures the hair or hairline unless worn daily for a religious purpose.
The digital file must be square, at least 600 x 600 and at most 1200 x 1200 pixels, JPEG, 24-bit colour in sRGB, no more than 240 kB, with a compression ratio of 20:1 or less.
If the upload fails, the FAQs say to bring one printed photo meeting the requirements with the confirmation page and to contact the Embassy or Consulate. If the confirmation page shows your photo, the upload succeeded.
Accuracy and the consequences of misrepresentation
INA section 212(a)(6)(C)(i) (8 U.S.C. 1182(a)(6)(C)(i)) makes inadmissible any alien who, “by fraud or willfully misrepresenting a material fact”, seeks or has obtained a visa, other documentation or admission. The clause sets no expiry for this ground.
Every DS-160 answer must therefore match the documents and facts — dates, employers, travel history and visa history. Inconsistencies between the form, the documents and the interview answers are where officers assess an applicant's credibility.
Correcting a submitted DS-160
According to the State Department FAQs, for a DS-160 submitted after 1 April 2010 the Embassy or Consulate should reopen the form if the application is refused for this reason. For forms submitted on or after 1 November 2010, the applicant enters the Application ID and answers additional questions as prompted to access and correct it. Reviewing every answer before signing is therefore the most important step.

I made a mistake on my DS-160. What now?
A submitted form can be corrected when the Embassy or Consulate reopens it; the applicant then uses the Application ID to access and correct it. Willful misrepresentation of a material fact is a ground of inadmissibility under INA 212(a)(6)(C)(i), so check every answer before signing.
