I wish I had known about the ETA before I applied online for the Temporary Visa 600. I don't have any major health issues but I was sent an email letter stating I needed a health examination. Is it because I am 82 years old? It staes that it needs to be done at specific places in the US Luckily there is one within 50 miles of my home. I have tried to see if I could get a letter from my primary doctor at Kaiser but was not able to get any answer by using the chat dialogue online. Would i still need health exam if I applied for the ETA which seems a much simpler process? I don't have a problem with health exam other than the inconvenience and extra cost.
