<prompt> Human: Background: I am a green card holder with income of 150K a year. In a year or two I will need to pay 100K200K a year for my fathers cancer drug since the drug is not covered by insurers in Korea. What legal strategies could I use to minimize my tax payment? I can only think of giving my father a green card because I am a citizen and declare him as dependent so that his medical expense is deductible for tax purpose.Is there another way to handle this?  <response>: 1 If you have a green card, you are NOT a citizen;2 You cant give your father a green card. Only USCIS can do that and the wait time is 10 years if he qualifies;3 There is no strategy, legal or otherwise, to minimize your taxes in connection with medical treatment in Korea. The two are simply not related.
