Trying to sort a visa for an international PhD can seem a bit overwhelming. After all, visas are exactly the sort of things that involve lots of very specific regulations and small print.
This blog has traditionally served as a sort of 'PhD visa 101', using the UK as an example.
A student visa is a travel permit that lets you enter a country to start a university course there. Once you've arrived you may also need a separate residence permit during your course (we'll come back to that).
The distinction between visas and residence permits is important because not all students need both.
Following on from the above, don't just assume you'll need a visa just because you're studying abroad. Lots of countries have agreements that mean their citizens can move freely between them.
The EU is one obvious example – you don't need a visa to go from one EU country to a university in another – but there are lots of others. For example, students from Australia don't need a visa to study in New Zealand (or vice versa). The Nordic countries also allow their citizens to study abroad freely at each other's universities. These exemptions aren't always obvious, so check our international study guides to be sure.
There's usually a time limit on how long you can stay with just a visa. To extend it, you'll need to pick up a residence permit. In the UK your initial Student Route visa will provide a sticker (known as a vignette) for your passport, then you'll need to collect a biometric residence permit (BRP) before that vignette expires (or within 10 days of your arrival – whichever is later).
If you don't need a visa, you may still need to register your arrival at a local police station or similar.
There are lots of regulations and requirements for student visas, but they mostly boil down to two things:
You may also need to take a language test, but this often happens when you're applying for a course (universities shouldn't 'sponsor' students without the necessary language ability).
The key takeaway here is to give yourself enough time. The likelihood is that you'll need to complete your PhD application and sort at least some funding before you can successfully apply for a visa.
Working whilst studying a PhD is fairly common and it's normally fine to do so on a student visa, bearing the following in mind:
As a PhD student it's worth checking whether employment with your university will count towards any cap on term-time working hours. It's pretty common for doctoral students to do some teaching work during their PhDs (or even hold full Graduate Teaching Assistantships). This will normally be fine, but make sure it doesn't take you over the limit for your visa.
You should also bear in mind that you can't normally rely on future earnings as evidence of financial support during your visa application. In most cases you've got to already have the money or be able to show that you'll receive it from a scholarship / studentship / etc.
You might be hoping your PhD leads to a career in the country you've studied abroad in. There's nothing wrong with that (I certainly don't think so) and most destinations have post-study visa options that will allow you to stay on whilst you look for work.
These vary, of course. Some countries, like Canada, are famously welcoming, with post-graduation work permits of up to three years following a PhD. The UK has also moved back to a more generous post-study work visa with a new three-year Graduate Route visa, which opened for applications last year.
