I have a 5.9 CGPA in my bachelor's. Can I apply to Arizona state university for MSIT?

Yes, you can apply to Arizona state university for MSIT. GPA isn't the only factor that is considered. Your whole profile is an individual matter. Your SOP. LOR and other tests and achievements majorly affect your admission to any university. 

Although the entrance requirements for each ASU's graduate program vary, the university has established basic standards for admission to its master's, certificate, and doctorate programs.

A bachelor's degree is necessary.

You must have obtained a bachelor's degree or higher from a U.S. university with regional accreditation or the equivalent degree from an international institution that has received official recognition from that nation.

GPA prerequisite

A "B" (3.00 on a 4.00 scale) grade point average in the most recent 60 semester hours or 90 quarter hours of undergraduate coursework is common for competitive applicants. The department may still examine your application even if your GPA falls below the minimum standards.

Program-specific additional criteria

Test results (such as the GRE or GMAT), the sort of curriculum taken during undergraduate studies, letters of recommendation, and any other supporting materials you may be requested to submit for your application may also be considered. To find out more about the criteria considered for acceptance, locate your program of interest on Graduate Degree Search.

Applications from abroad

Except for providing evidence of English language competency, the application requirements for overseas students are the same as those for domestic students (for students whose native language is not English). International students must submit a graduate financial guarantee to receive a U.S. visa after being accepted.

All international transcripts must be supplied with an official English translation and in the original language. The translations must be accurate replications of the original texts, done by a university, a representative of the government, or an authorized translation firm. You cannot finish the translation yourself.

Transcripts that have been notarized or copied are not acceptable.

Hopefully, this will help. These are the basic criteria that need to be fulfilled by every student for any course they are applying for. But still, it is recommended to check the requirements from the official site to avoid any confusion.
