Estate Planning for Permanent Residents and Citizens: Korean families who have lived in the U.S. for a long time often still have assets remaining in Korea. These can include an apartment in Seoul, fixed deposits in Korean banks, a share of rural land inherited from parents, along with assets in the U.S. such as a house, a 401(k) retirement account, and life insurance, all belonging to one family. While these assets may seem manageable during life, after death, they will each be subject to the laws, registration offices, and tax authorities of different countries.
