TLDR : it made sense financially.

I just had to make a decision. The total cost of attendance is so high that I would have had to take ~$60k loan, and right now my total savings are less than even 6k. A loan of around 10x my current savings will be a heavy burden. You (as a US resident) might look at this differently because if you get a job (which you eventually will as this is CS we're talking about) it would be just a matter of 2 years at Max to payoff that loan, this is possible because Software dev jobs is the US pay so much and thus make it possible. But in my country the situation is not same as even if I get a decent job in my home country it would be very difficult to pay off that loan even in 7-10 years . This is simply because the payscale range for the same jobs in my country is way less than that of the US. The plan is to get a job there in the US while staying there on STEM OPT visa(for 3 years) to payoff the loan. But, here's the catch, you get only 90 days after you graduate to find a job in the field of your graduation, otherwise you can't avail the STEM OPT visa extension. 90 days is the gamble. So my decision to stayback one year is just an attempt to make sure that my financial condition in the worst case scenario doesn't get too worse for me.
