Is it difficult to get into the University of Arizona?

Yes, international students are required to get their degrees evaluated from a credential evaluation service like the WES. This should have all the courses, units, accreditation of the university and all. Look at the documents given below other than this one admission requirement - 

• A UG degree 
• English proficiency proof
• Entrance exam for some courses 
• A good GPA
• Documents like SOP, SOR and more

The students are first required to follow the University of Arizona admission process to be able to submit the application here. The students will receive an email from the university in case of a decision. 

The students will be receiving a notification for the same. Also, they can easily check the application  status by logging on to their admission portal. 

After submitting the University of Arizona application, international students can expect to get an acceptance letter and the application decision within 2 to 6 weeks. 

It is when all the admission material is submitted. Also, it may depend on the type of intake as well, like if you have applied for a Fall intake (Early Action), you might hear from the university in mid-Jan. 

At the University of Arizona, there are two main intakes which are the Fall semester and the Spring one too.  For the Fall one, the students are encouraged to apply in the months of August or September. 

One smaller intake named the Summer is also available but not many courses are open then. The students can make application in the month of May for the same.

Earlier yes, the University of Arizona used to have a rolling admissions system for all its international students but now it has shifted to a new system of priority and regular admission deadlines system. 

Now, this university encourages students to apply by the month of Nov 1 every year for the Fall entry. And for UG admissions via the regular decision, a little later.
