The only ranking that matters is the overall university ranking(US News) and IU is ranked #83 this year. I graduated in a Uni in the top #20

I have been back in Singapore for 4 years.

I would only spend that 150k on a US education if:
1) You can get into a top #30 University(overall ranking).
2) Using this 150k will not affect your parents' living standard one bit.

I will definitely not spend 150k on IU.

Career wise, having a US degree and work experience has helped me. I have gone for interviews where the US recruiter chose my resume because of a familiar school name on my resume. One recruiter even said this to me: "I received tons of resumes from PRC/Indian students in Singapore and from their resumes they look like very qualified technical candidates. However, I need someone who can liase on a personal level with the US counterparts and have strong language skills. Many of the PRC/Indian candidates fail in this area".

Having US work experience looks nice on my resume too and puts me one notch up from local candidates.
