Okay, so you're worried because the photos you used are different sizes and you're planning to use yet another different one on your admit card. I understand your concern! Here's the deal: it's really important that your photos are consistent throughout the whole application process. Basically, when you submit your application, the photos are key to accurately identifying you and making sure everything goes smoothly during verification. If there are differences between the postcard and passport sizes, and the one you stick on the admit card, it could raise some red flags. This can potentially lead to problems like your application being rejected , or you might face extra scrutiny when they're verifying your identity later on. Why is this so important? Well, having the same photo across all your application materials helps the people reviewing everything to easily confirm that you are who you say you are. If the photos don't match up, it can cause confusion and slow things down. In some cases, it could even lead to you being disqualified – and nobody wants that! To avoid all this hassle, the best thing to do is use the exact same, recent photos for everything . Make sure they meet all the specific requirements mentioned in the application guidelines, too. Doing this not only makes the verification process faster and easier, but it also shows that you're paying attention to detail and following the rules, which always makes a good impression . I hope you find this answer helpful, feel free to follow up with any further clarifications.
