I need advice

Have you told your step-sister about your plans? Would she let the girls go with you? Would your sister allow you to adopt them? Would not going make you regret having the girls? The girls will be difficult at times and it’s easy to say you’ll never regret it, until they are horrible to you for a week and you’ve had no personal time. Not saying you stop loving and caring for them but parenting is hard. You will lose a part of yourself for them. Do you have other family in the area to help support you? Would you have family/friend support in Korea? What would be best for the girls and what is best for you? Would the court let you foster the girls based on your age, status and relationship to them? I would ask family their options and do a whole lot of praying. Please keep us posted.
