ASU - waiting for decision

[CPV]

I am an international student and am applying for MS in Computer Science, Fall 2017. Till now, I've got only 1 admission letter, which is from UIC. I expected to get another one from ASU. So I mailed them (both the university and the department) last week and they replied that it's still under review and that they expect to make admission decisions till the end of May. Nothing was mentioned about wait-listing and rejection.

 

Now, my question is, should I wait for their letter? The deadline for UIC is May 15th and I'm already getting fidgety. I have to arrange for a student loan, housing, accommodations, resigning from job, packing, visa and all that stuff. So I accept the letter from UIC and not wait for one from ASU (despite my high hopes of getting in)? Has ASU already made their decisions?
