I,  as an aspiring student, completed my engineering in 2020 and now want to increase my scope of knowledge by studying further in the most prestigious university in USA or Canada. I took a year gap after my engineering to attempt my GRE exam. but, I am now facing an issue with the justification of the gap after my engineering when I applied for a student visa. I want to approach in an honest way. How much gap is acceptable in USA and Canada. Someone, please suggest to me some tips to face visa interview and justify the gap after my education. Thank you.
