I have similar situation with KK0609, I still haven't made up my mind yet to pay the fee USD380 for each person, I have 2 kids and my hubby and I want to ask,
1) once we got approved by US immigrant, can we just land US for about 1 week ? b/c my hubby & I have jobs in HK and my kids are still having education here.
2) after landed, say for 1 week only, then we want to go back HK to continue our work and school, it is ok for us to go back US once a year, will it be still OK for a green card holder ?
3) when my kids study in US, green card holder can ejoy the citizen's school fee ?
4) Do green card holders need to pay the tax in US ?
