At their pre-consulate green card interview health check, my in-laws were required to have a number of vaccinations. They did all of these. For chickenpox, the doctor gave them a shot and then checked a box on the vaccination sheet to say that a booster was due 1 month later. But there is a note at the top of the sheet saying that if the applicants are unable to travel back to this US gov-approved doctor due to cost, distance, etc. they can wait until they get to the US to get the booster.
It is looking as if they will not be able to come to the US until the spring, about 4-5 months after the health check. They also live a 3-hour airplane flight away from the city (Guangzhou) in their country where their health check was conducted. Does anyone know if their vaccination record will be checked at the border when they fly to the US and if the lack of the booster shot will be an issue? Per the note on the sheet, it should not be given the distance, but I want to make sure that the fact that they are 3-4 months beyond the 1 month booster shot date will not be an issue. Thank you!
