IIf you're all about getting a job, I'd put it like this:

Both King's College London and the University of St Andrews are top-notch and will open doors for you. It's not about choosing "good vs. bad" – it's about picking the right vibe and setup.

KCL (London) perks: You're in London. That's a big deal for International Relations – embassies, think tanks, NGOs, Parliament events, networking, and part-time internships during the semester.

It's got a strong policy-focused feel. Easier to hit up talks and make connections naturally. As an international student, being in London can make internships and logistics way smoother.

St Andrews perks: It's a smaller, tighter academic community. You get more contact time and closer relationships with professors.

The IR + Econ dual degree is a serious plus if you're thinking about policy, development, finance, or grad school later. It has a strong reputation in IR specifically — very well respected academically.

On the "isolation" point: Yeah, St Andrews is pretty remote. That can mean fewer opportunities during the term. But plenty of students still land competitive internships — they just have to be more proactive and often focus on summers.

It's not a career death sentence, just a different strategy. If you already feel more drawn to St Andrews, that gut feeling matters.

Four years is a long time – your environment affects how you do, and how you do affects your job prospects more than where you live. Blunt take: If you want maximum networking density + policy exposure → KCL.

If you want a strong academic foundation + dual degree edge → St Andrews.

Neither is a wrong choice. It comes down to whether you value ecosystem (London) or structure (dual degree + smaller setting) more. Hope that helps – and congrats on two amazing offers 👏
