Overview
The email lands, you open the PDF, and there it is, your name next to the words you have been waiting months to see. And then, almost immediately, a second feeling shows up right behind the relief, because the letter is full of terms that were not part of your vocabulary a week ago. Conditional. Unconditional. CAS. I-20. Confirmation of Enrolment. None of it is complicated once someone walks you through it in order, but I understand why it feels overwhelming in the moment, because this is genuinely the stage where a strong application can still stall if the sequence gets confused.
So let me walk through exactly what happens next, and in what order, because getting this sequence wrong is one of the more common and more fixable mistakes I see.

Is Your Offer Conditional or Unconditional, and Why Does It Matter So Much?
This is the very first thing to establish, because it determines almost everything else about your next steps. A conditional offer means the university wants you, but your place depends on meeting specific, stated requirements before it becomes final, most commonly a final grade threshold, a required English proficiency score, or outstanding documents like a final transcript or reference letter. This is genuinely the norm rather than the exception, the majority of international students receive a conditional offer at some point in the process, particularly if they applied before final exam results or English test scores were available. It is not a signal of a weak application, it is simply how most universities handle timing.
An unconditional offer means you have already met every academic and language requirement the university needs to see, and your place is confirmed outright, with no further academic hurdles standing in the way. This is the offer type that actually unlocks the next stage of the process, since almost every immigration authority worldwide requires an unconditional offer, not a conditional one, before you can move forward with a visa application.
If your offer is conditional, your very next task is to identify every single condition listed, note the exact deadline attached to each one, and start working on them immediately rather than waiting for exam results or documents to arrive on their own. Universities generally prefer to hear from you early if you expect a delay meeting any condition, rather than discovering a problem right at the deadline.
What Happens Once Your Offer Becomes Unconditional?
Once your offer is unconditional, either because it started that way or because you met every condition attached to it, a fairly consistent sequence begins across most destination countries, even though the specific paperwork differs.
First, you formally accept the offer, usually through the university's own portal or, in the UK, through UCAS if that was your original application route. Second, most universities will ask for a tuition deposit at this stage, not before, commonly in the range of ten to twenty percent of first-year fees, though the exact figure and currency vary significantly by university and country. This deposit is usually non-refundable, so read the university's specific terms carefully before paying, particularly around what happens if your visa is later refused.
Third, once your deposit clears, the university issues the specific document your destination country's visa system actually requires, and this is where the terminology splits by country. In the United Kingdom, this is the Confirmation of Acceptance for Studies, or CAS, an electronic reference number that links your accepted, unconditional offer directly to your Student visa application, and it is generally only issued within three months of your course start date, so do not expect it the moment you pay your deposit. In the United States, this is the Form I-20, issued once your enrollment and funding documentation are confirmed, and it is the document your F-1 visa application is built around. In Australia, this is the Confirmation of Enrolment, or CoE, issued once your acceptance and deposit are processed, and it is what your Student visa application will reference.
Only once you hold this specific document, CAS, I-20, or CoE, should you begin your actual visa application. Starting the visa process before this document exists is one of the more common timing mistakes I see, since none of these visa categories can be processed without it.
What Should You Actually Be Doing in Parallel?
While your unconditional offer moves through deposit payment and document issuance, this is also the window to get your financial documentation genuinely visa-ready, not just gathered. Most visa authorities want bank statements and sponsor letters that are recent, generally no older than one to three months at the point of your actual visa submission, so avoid finalizing this too early and letting it go stale before you need it. If you are applying for an education loan, note that banks and financial institutions overwhelmingly require an unconditional offer, not a conditional one, to process the loan, so this is also the moment to start that conversation if you have not already.
This is also a sensible window to start on Overseas Student Health Cover if you are Australia-bound, since many universities require proof of this before issuing your Confirmation of Enrolment, and to begin researching accommodation, since popular options near your specific campus fill up faster than most students expect once results season is underway.
What If You Are Holding Offers From More Than One University?
If you applied to multiple universities and are now comparing more than one offer, decide and communicate your decision reasonably promptly. Declining offers you will not use, cleanly and through the proper portal, is common courtesy, but it also matters practically, since holding multiple live offers can occasionally slow down deposit processing or document issuance at the university you do intend to attend. Compare offers on the full picture, not just the headline decision, total cost including realistic living expenses, the specific conditions attached if any offer is still conditional, and how each university's own document issuance and visa support timeline lines up with your intended start date.
What Mistakes Do I See Most Often at This Stage?
Paying a deposit before actually reading the refund policy attached to it, then discovering later it is non-refundable even if a visa is subsequently refused. Assuming a conditional offer means rejection is likely, and consequently not moving fast enough to submit the outstanding documents or results the moment they become available. Trying to start a visa application with only a conditional offer or before the CAS, I-20, or CoE has actually been issued, which simply is not possible in most visa systems. And letting financial documents sit untouched for months after gathering them, so that by the time the actual visa submission happens, the bank statements are already too old to count.
Frequently Asked Questions
What is the difference between a conditional and an unconditional offer letter?
A conditional offer means the university has accepted you provisionally, subject to meeting specific requirements like final grades, an English test score, or outstanding documents. An unconditional offer means you have already met every requirement and your place is fully confirmed with no further academic conditions attached.
Can I apply for a student visa with a conditional offer letter?
No, in almost every major study destination. You generally need an unconditional offer and the corresponding document, a CAS in the UK, an I-20 in the US, or a Confirmation of Enrolment in Australia, before a visa application can even begin.
When do I need to pay my tuition deposit?
Only after your offer becomes unconditional and you have formally accepted it, not before. Most universities will specifically request the deposit at this stage, and it is commonly ten to twenty percent of first-year tuition, though this varies by institution.
What is a CAS, I-20, or Confirmation of Enrolment, and when will I receive it?
These are the country-specific documents, CAS for the UK, I-20 for the US, CoE for Australia, that your university issues once your offer is unconditional, accepted, and your deposit is paid. They are what your actual visa application is built around, and a CAS in particular is generally only issued within roughly three months of your course start date.
What happens if I fail to meet the conditions on a conditional offer?
The university can withdraw the offer, though many will consider a near-miss on results or a slightly short English score, and some offer alternative pathways or foundation options. Contact the admissions office as early as possible if you expect to fall short, since universities generally prefer advance notice over a deadline-day surprise.
