What do I need to know before filling the DS-160 form for a US visa?

By Shachi Mall· July 16, 2026Updated July 2026· 4 min readDS-160 Form

The DS-160 is the only document the US visa process requires you to submit — and it is the exact form sitting in front of the visa officer when you walk into your interview. Getting it right matters more than most applicants realise, and there are five things you should know before you type a single word into it.

1. Save your application ID and security question the moment you start

As soon as you open a new DS-160 application, the system will ask you to set a security question and will display an application ID on the screen. Do not skip past this. Every time you return to your application, you will need both of these to pick up where you left off — because the DS-160 auto-saves on the consular website, but you can only access that saved version if you have your application ID and the correct answer to your security question.

For the security question, you will be given a list of options — things like your mother's maiden name or your place of birth. Pick whichever one you will remember easily, and make sure you remember the exact answer you give. For the application ID, there is a save button right below it on the screen — click it and save a PDF to your laptop. If that is not convenient, just take a photograph of the screen and save it on your phone. Either way, do not lose this information.

2. Block 60 to 70 minutes and do it in one sitting

The DS-160 is a six-page document with a lot of questions. My strong advice is to complete it in one continuous sitting rather than spreading it across multiple sessions. Here is why: if your system sits idle for more than 15 minutes, the application will automatically log you out. You will then have to log back in using your security question and application ID, find your place again, and get back into the flow. It is frustrating and it slows everything down.

Block 60 to 70 minutes of uninterrupted time before you start. That window is enough for most people to get through the entire form without being rushed, and you will not have to keep breaking your concentration by logging back in.

3. Prepare your answers before you open the form

Several questions in the DS-160 are descriptive — they ask you to write a paragraph or two, not just tick a box. If you try to think through and compose those answers while you are actively filling the form, two things happen: the process becomes slow and stressful, and you risk the system timing out on you while you are still typing.

The smarter approach is to draft your answers separately, before you even open the form, and then simply paste them in when you reach those questions. The work information section is one of the most important parts of the DS-160 and one of the sections that catches people off guard. Having those answers ready in advance makes the whole process faster, calmer, and much less likely to go wrong.

4. Keep your old DS-160 forms nearby for reference

If this is not your first US visa application, you have filled a DS-160 before — and you should have a copy of it. Pull it out and keep it with you while you fill your new form. The information across your old and new DS-160 needs to be coherent and consistent. You cannot give contradictory data between two forms, and doing so will create serious problems during your interview.

This is especially important for three categories of information: details about your family, your work history, and your travel history. These are things that are not expected to change, and a visa officer will notice if the answers suddenly differ from what you submitted in a previous application. Having your old DS-160 in front of you makes it easy to cross-check as you go.

5. Save your completed form — do not just close the browser

Once you have reviewed everything and hit submit, the system will ask you to provide your e-signature and will then display a confirmation page. That confirmation page is what you bring to your visa interview, so save a copy of it and print it out if you can.

But here is the step that a lot of people miss entirely: before you close your browser, save or print a copy of your entire completed DS-160 form. The browser gives you an option to do this — use it. You will need this form to prepare for your interview. Your DS-160 might be submitted two or three months before your interview date, and there is no way you will remember every single answer you gave. When you sit down to prepare your interview responses, your DS-160 is the document you work from. If you do not save it, you will not have it.
