My wife took all of the precautions, including an X-ray 1 month prior, which she passed, she took vitamins, exercised, milk x 1 week and other meds. Went to medical, got flagged for sputum, along with about 80% of the others, she said. had to go back 2 weeks later for the 4 days, including the day off for holiday and just finished today. She now has to wait until July 1st to go back, if nothing shows up negatively. Then she has about 1.5 months after that date to get in the US, along with her son.
