I'd prefer to take any of Cambridge English (Advanced, First). Their qualifications are for life.

TOEFL is only valid for two years.

Source: I'm taking Cambridge First this year, probably October or November.

I think IELETS for UK universities 

Cambridge english test is only for the UK or for all over the world? I mean.. Is toefl test valid for the UK too or just american? 

No, but I think it is always a good thing to take a test so you can be sure about your level.

I did TOEFL ITP and I intend to do TOEFL iBT in the next few months
