The I-20 and SEVIS fee have a fixed order.

The United States route looks like more steps than it is. What makes it feel difficult is that the steps are strictly ordered, and each one consumes an identifier produced by the one before it. Do them out of order and you are not delayed, you are blocked.

The chain, in order.

1. 01The student is admitted to a school authorised to enrol international students.
2. 02The student sends the school proof of finances and identity documents, in the form that school asks for.
3. 03The school issues the Form I-20, which carries a SEVIS identification number.
4. 04The student pays the SEVIS fee, using the identification number printed on the I-20.
5. 05The student completes the online non-immigrant visa application, entering the same identification number and school code.
6. 06The student pays the visa application fee and books an interview at the appropriate post.
7. 07The student attends the interview, carrying the I-20, the fee receipts, the application confirmation and the financial evidence.

The identifier is the thread. It is created at step three, spent at step four, and re-entered at step five. A student who pays the fee before the I-20 arrives has nothing to pay it against. A student who books an interview before the fee clears may arrive at a post that cannot confirm payment.

Where agencies actually lose time.

The financial documents are sent in the wrong shape.

Schools do not all ask for the same evidence, and the I-20 will not be issued until the school is satisfied. Collecting a generic bank letter and hoping is the single most common cause of a two-week stall. Read the school's own checklist for each admission, and store it in the student's file so the next counsellor does not have to find it again.

The name does not match the passport.

Surname and given-name order, diacritics, a middle name that appears on the application but not the passport. Every one of these has to be reconciled before the I-20 is issued, because correcting it afterwards means a reissued form and, in some cases, redoing steps that referenced it. Check the passport page against the application at the point of admission, not at the point of interview.

Nobody watched the programme start date.

The I-20 carries a programme start date, and both entry timing and the interview window are anchored to it. A student who is admitted late in the cycle may find the interview calendar at their post cannot accommodate them before that date. When that is a real risk, ask the school about deferral to the next intake early — a deferral requested in good time is routine, and one requested a week before travel is not.

Preparing for the interview honestly.

The interview is short and it is about the student, not about your agency. Preparation means making sure the student can explain their own choice: why this programme, why this school, how it is being paid for, and what they intend to do afterwards. It does not mean a script, and it never means an answer the student cannot support.

A student who has been coached into someone else's answers performs worse than one who is nervous and truthful, because the follow-up question is where the coaching falls apart. If a student cannot yet explain why they chose the programme, that is a counselling problem to fix before the interview is booked.

What the file should contain at the end.

• The admission letter and the school's own document checklist for that admission.
• The I-20, with the version history if it was reissued, and the reason it was reissued.
• The SEVIS fee confirmation and the visa fee receipt.
• The application confirmation page.
• The financial evidence in the form the school and the post asked for, with a note of who verified each document and how.
• A dated record of what the student was told at each counselling session, including what was said about outcomes and about costs.

That last item is the one agencies skip, and it is the one that matters most when something goes wrong. A refusal is survivable. A refusal where nobody can show what the student was told, by whom, on what date, is a complaint you cannot answer.

Requirements, fees and processing times change. Check the current official guidance for each step before you advise, and note the date you checked.
