Although we commonly refer to IQ by raw numbers, they can be confusing because there are different tests and different scales. For example, in the US the usual standard deviation applied is 15 or 16, but in Europe it is 24 or 25. Thus an IQ of 130 in the US can be equivalent to an IQ of 150 in Europe.
The minimum entry level for Mensa in the UK (placing someone in the top 2%) varies according to the test:
Cattell III B - 148
Culture Fair - 132
Ravens Advanced Matrices - 135
Ravens Standard Matrices - 131
Wechsler Scales - 132
I believe that the Wechsler (WISC III/IV) tests are most often used in the US, while Mensa uses Cattell and Culture Fair, noting that a middle-aged adult cannot score more than 161 on the Cattell test.
