I get messages every week from students who have done almost everything right — prepared their answers, gathered their financials, rehearsed their story — but then hit a wall because of a mistake in one of these three basics. Your I-20, your SEVIS fee, and your DS-160 form are the three cornerstones of your F1 visa journey. Everything else you prepare sits on top of these. If any one of them has an error or is missing, it can result in a rejection at the window. Let me walk you through each one so you can make sure yours are fully sorted.
Your I-20: The Single Most Important Document in Your F1 Journey
Your I-20 is the single most important document in your entire F1 visa journey. Everything begins once you have it in hand. After you receive your admission letter from the university, you will need to log into the university portal, fill out a few basic details, attach proof of your funding, complete any additional forms required, and submit. The university then processes and issues your I-20.
One thing many students underestimate is how long this can take. Processing time varies significantly from school to school — some universities issue the I-20 within a week or two, while others can take up to two months. Factor this into your timeline before you plan to book your visa slot. If you are still waiting for your I-20, be proactive. Follow up regularly with your school official or admissions coordinator and let them know you are eager to begin your process.
How to Check Your I-20 Once You Receive It
Once your I-20 arrives, do not just file it away. Do a line-by-line check. Universities do make mistakes, and catching them early saves you a lot of trouble. Here are the key fields to verify:
Name: Your given name and surname on the I-20 must match exactly what is written in your passport. Even a small discrepancy matters.
Date of birth: This must be accurate and match your passport details exactly.
School name: Usually correct, but worth a quick check.
Program of study: Confirm that the correct course is listed. Keep in mind that the course name on your I-20 may not be worded exactly the same as in your admission letter — universities often follow a standard naming structure. For example, a Master's in Business Analytics might appear as 'Quantitative and Financial Methods' on the I-20. This is fine, as long as the overall field of study is correct.
Financials: This section is critically important. Check that all figures are accurate. Also verify that the expenses listed are only for you — sometimes universities accidentally include dependent expenses even when you have no dependents.
Funding and scholarships: If you have a scholarship or any kind of assistantship, it must be listed in your I-20. The visa officer will only consider it during your interview if it appears on this document.
Student signature: There is a signature field for the student. You need to sign it before your visa interview — there is no specific deadline for this, any day before the interview works. If you are under 18, a parent signature is required instead.
The SEVIS Fee: Do Not Show Up to Your Interview Without This Receipt
Your SEVIS ID is a unique identifier printed on your I-20. It is issued to every international student entering the US for education. You must pay a SEVIS fee linked to this ID, and carry the fee receipt with you to both your biometrics appointment and your visa interview. This is a mandatory document — not optional.
I have spoken to students who completed the entire visa process — prepared thoroughly, went to the interview — but were rejected simply because they had not paid the SEVIS fee. They either forgot or were not aware it was required. Please do not let this happen to you. Make a note of it right now: pay your SEVIS fee.
How to Pay the SEVIS Fee

Book a Mock InterviewGo to fmjfee.com. You will see a clear option to pay the I-901 fee — that is your SEVIS fee. Click on it and enter your SEVIS ID, last name, given name, and date of birth exactly as they appear on your I-20. Once you submit, you will be asked to pay $350, which is the current fee for an F1 visa. After payment, save and print your SEVIS fee confirmation receipt. This is what you bring to the interview.
One more thing: if you are applying for an emergency or expedited appointment, paying your SEVIS fee beforehand is important. Attach the fee receipt as part of your expedited appointment application.
What If You Switch Universities After Paying?
If you have already paid the SEVIS fee for one university but later decide to go with a different admit, you do not need to pay again. The SEVIS fee can be transferred. Write an email to the SEVIS support ID explaining that you want to transfer the fee and provide details of both universities. This transfer typically takes about three working days, and it must be completed before your biometrics and visa interview.
The DS-160 Form: Fill It Carefully — It Is the Only Document the US Visa Process Asks You to Submit
The US visa process does not require you to submit any documents upfront — except the DS-160 form. That fact alone tells you how important it is. Filling it accurately is non-negotiable. Every factual detail must be correct, and you need to take extra care with the work and education sections, because those are the sections the visa officer reads most closely.
Work Section: Keep It Concise and Structured
When the visa officer reads your work section, they should get a clear, immediate picture of your roles and responsibilities. If you are not currently employed, the description field should explain what you have been doing during any gaps — whether that is studying, personal projects, or anything else relevant.
One of the most common mistakes I see is people writing extremely long, unformatted work descriptions. The DS-160 form does not allow you to format text, so everything runs together. A long block of text with no structure is almost impossible for the officer to read quickly. Instead, split your work description into three to four bullet points with concise, precise language. Make it easy to scan.
Education Section: Start From the Highest Qualification
For education, start with your highest qualification and work backwards. Include everything — your Master's or Bachelor's degree, your 12th standard, your 10th standard. List them all in order.
An Important Tip for Booking Your Appointment Slot
You do not need to complete and submit the entire DS-160 form before you can book your visa appointment. All you need is a DS-160 confirmation number. Start filling out the form, get the confirmation number, and use that number to begin booking your slot right away. Do not wait until you have finished the full form before you start the booking process — appointment slots are not always easy to get and it can take multiple attempts. Get your confirmation number first, then continue filling out the rest of the form while you search for a slot.
