Hi, I would check with the consulate of whichever country you are thinking to work in. In some of EU, (in Italy for sure) you need to be a qualified beauty therapist with state recognised qualifications (ie NVQ L3 + / ITEC L3 + / CIBTAC-CIDESCO ) before you can carry out treatments, lashes may be considered a specialised certificate taken after initial beauty therapy training. it often works differently from the UK, check that your qualifications are recognised for conversion in the country. Am not sure about Spain but in the US I believe you need a licence which varies depending on which state you are in. Hope this helps. x
