USA

For Indian students who are applying for a U.S. student visa to study at Iowa State University, several documents must be provided. These documents include a valid passport, the I-20 Form that was issued by the university, and the completed visa application form, that is, DS-160. Additionally, a receipt of visa application fee and SEVIS fee payment along with a passport-sized photograph will also be required. Additional documents include academic transcript and certificates, proof of proficiency in English (e.g., IELTS, TOEFL), proof of financial resources demonstrating available funds for tuition and living expenses. It is also essential to submit standardized test scores if those are required by the programme of study. Check Iowa State University's website and U.S. embassy for the most updated requirements.

The University of Dayton (UD) is comparable to other universities of Ohio, especially to its peers such as Ohio State University (OSU) and Ohio University. Some comparisons on key points are listed:
Tuition and Financial Aid: UD tuition is around $39,090 while the OSU in-state tuition is at $10,037. Yet, UD offers financial aid to the tune of about $20,822 that is more than the average amount OSU disburses in financial aid of around $8,481.
Acceptance rates: UD has more significant acceptance rates at 58% than OSU that has a 49%, so generally, a greater percentage of students receive admittance to UD.
Student Body: Underclassmen enrollment is also lower, around 8,556 for UD; therefore, campus feels slightly more intimate than its counterpart of 44,131 students at OSU.
In a nutshell, UD has much higher tuition, but their great financial aid packages and programs that are tailored toward academics make it an excellent fit for students in Ohio.
