How many hours you work per day? What time do you usually get out office???

I guess i'm bit late for this. Anyway the average is 10-12 hrs daily but depends where you practice and also depends on the people you are working with. I seldom works on weekends too.

ok thanks so for sure it's not the work for me...:)

broadly speaking, I don't think an international tax lawyer works more (or less) than an other kind of lawyer... it just depends on your firm (and motivations)

of course not , 10 hrs a day is the average day of lawyer regardless the field of expertise . Anyway if you can't handle I guess law is not for you not just tax field.

the question is not if I can handle it or not, the question is that I don't want....I would have a bit of free time to spend with my friends now and eventually with my family in the future..
As I hold a degree in law I'm wandering which kind of job suits better for me...
