Moving abroad is a big step for many expatriates, but the decision to return home can be just as difficult, and picking the right moment is vital.
Many expats living in South Korea have started to contemplate the fact that tensions are rising between the country they have begun to call home and its closest neighbour to the north.
Around two per cent of South Korea's population is made up of foreigners with an estimated 22,000 of them English language teachers.
It is now up to them to decide whether it is safe to stay and continue their lives in the country or look for a job elsewhere.
Some expats have been impressed by the way that citizens have seemed unphased by the perceived increased threat and this has made them feel safer.
Vincent Van Wattum, an American teacher in South Korea, told CNN: "Reactions are non-existent at the moment. My co-teachers and I have never discussed it and it never comes up among Koreans in general conversation.
"Just in case, I packed a light bag, ready with my passport, some cash and a change of clothes ready to go if I need to get out of Dodge."
