Can I buy US life insurance if I plan to move back to my home country?

You can buy US life insurance while you live and work here, and many term policies remain in force even if you later move abroad, as long as you keep paying premiums and the policy was issued while you were a US resident. Confirm two things with the insurer before buying: whether the death benefit will still be paid if you die overseas (most do pay worldwide), and how you will make premium payments from abroad, since some require a US bank account. Extended travel or relocation to certain countries can complicate claims, so read the policy's residency and travel provisions. If a future move is likely, tell the agent up front so they can steer you to a carrier with favorable expat terms.
