Hi! I have lived and studied abroad in several countries over many years. In my many years abroad, I have learnt a lot, by being in the shoes of a student, an employee, and just a tourist. I felt like sharing everything I have learnt over the years with people who are aspiring to go abroad to study or settle. You are welcome to send me your queries and I shall do my best to answer them to the best of my knowledge. Here’s to your Way Abroad!
