I hear you... I'm still not fully decided. I think US education is seen as more prestigeous and as mentioned before, it would look good on a CV, showing that I went out of my way to learn.
Places I could go are fairly numerous; the problem is how to choose. In the UK, you apply for two offers: a Firm Offer and an Insurance Offer. If the Firm Offer falls through (too many applicants, too late, grades not good enough, etc.) you have the Insurance Offer to fall back on. That's as far as I understand it. There are no application fees up-front. The price is around £9,000/year for a good university, and for a four year M.Eng course, I'd be at least £36k in debt just in tuition - before considering living expenses (food, electricity, driving/transport...) of at least £4,000/year, if not more. Although most of this is paid by student loans, you still have to pay these back, although the interest rate is very low (maybe even 0%?) and you only pay them back when earning >£25,000/year at 9% of your income... which is still a lot... because you'd already be looking at 20% income tax... so almost ~30% tax. Which is a lot.
In the US, as far as I understand it, competition is fierce but international students are regarded on the same ground as domestic students. My favourite is MIT, whose sticker price is ~$55,000/year, but Carnegie-Mellon, Stanford, and Caltech are under consideration, and the price is about the same, around $60k/year. Way more than the UK, but as my family earns less than $120k/year (might even be less than $75k/year) I'd have to pay only about $4,400 of this a year - the rest is covered by scholarships and grants. The problem with this is that $4,400 is only tuition (excl. living expenses) and is still a lot of money, so I'd need part-time work to cover it. Then living expenses come into the equation. As far as I know student loans can be funded by government or by private banks, but there's the risk you can't pay it back: in the UK, it would be written off by the government if you can prove you are unable to pay after 15(?) years, whereas in the US you could have debt collection agencies on your tail. And with US universities there's no "UCAS" system, which means you have to apply individually to universities, and they each want $70 to $200 application fees. At least MIT lets you apply to waive this fee. It's a lot of money to apply for something that might fall through.
Another thing is that credit cards seem to be a big part of the student lifestyle. I have seen what excess credit has done to my family (both mum + partner in debt a lot... double figure thousands), so if I can, I would like to avoid them: it's too easy to spend beyond your means. But it might not be an option.
Then of course to live in the US, you need your plane ticket there, and I'd like to take my stuff if I can (oscilloscope, test equipment etc.) Some of it is 230V only. Shipping could be expensive. I'm only 17 and will be 18 or 19 going to university, so it would be a big change, and may take some getting used to.
Oh and there are student visas, insurance etc. which all needs to be sorted out.
Does anyone have any experience about this? Any suggestions?
