Help to choose between aml compliance profession and governance profession.

Hi, as the title says, it is often so difficult to choose between different careers as we don't have direct exposure into it unless we actually choose them and starts working them. Myself an international student in UK, studying LLM along with Chartered Governance qualifying programme. Being in a corporate legal profession seems to be very rewarding and glamourous, now i worry that it is more like a tedious secretary role and heavy paper work, and if i couldn't secure a sponsorship visa within 2 years, the whole qualification thing is goin to waste. so i was thinking about changing to AML compliance role, which seems to have much more opportunities, and pays decently. moreover i hope it gives flexibility work in other countries, so no worries regarding visa. But now my concern is about how good is AML compliance jobs? what are they in day to day works like? . etc. someone has any idea....please help
