Is it really a bad idea to do a Masters before doing graduate in the U.S?

[icma]

Hi,
I've read and been told that it's not a good idea to do a masters (in Europe) before doing a graduate course in the U.S. Is it really a bad idea? would it reduce the chances of getting a place in a graduate program or is it just that it's not required? I understand that it might be repeating some stuff but surely if I've already covered it I can find something else to do? or even start the research early?
Also since my BA results will come in a considerable while after application deadlines in the U.S will I still be able to apply for that year?
If not is there any harm in doing a masters in that extra year or should I find something else to do?
Sorry for asking so many questions,
Thanks,

I don't think it reduces your chances at all, in fact it may improve them if your grades are decent during the msc. I see a lot of graduate students from the EU and India often get admitted into US grad programs with a MS. under their belt, just look through department webpages. If a MS can expose you to research then it is a really, really good idea, as in the EU it's pretty hard to get research experience as an undergrad.

You probably wouldn't be able to apply for the same year though.

+1. There are no such things of REUs 'round here.

Although they aren't so popular I've come across some, also it seems a few American REUs (http://www.surf.caltech.edu/index.html) take international students.
