Hey! I’m from China but I’m an international student in US for six years now. I studied abroad in England for a semester and I would say if you are able to get an offer and proficient in English, it’s not hard. But for me personally as an international student in America, even though I am extremely fluent in English to the extend that I have zero accent and fully capable of understanding everything, I did struggle to understand some British accent especially when they speak fast. However, if you are familiar with British accent and able to get an offer, forget everything I just said. UK is beautiful and I miss it so much.
