Hi, I am a US citizen currently living in Australia. My son is also a US citizen, and my husband is not, but has just been awarded a green card. We are returning to live in the US in June, but we are unsure of length of stay. Possibly 2-3 years. We will have travel insurance from an Australian company for the first year. Would we be eligible to buy visitors insurance from you after we have already been in the states for a year?
