I'm a US citizen applying for a 6mo visitor visa, but I'll be traveling from Southeast Asia, and so am required to have a health exam and chest x-ray. The only clinic in my current country that does both the exam and the x-ray was fully booked several weeks out, and I was only able to get an appointment for the 28th day after receiving the letter requesting health exams, which of course says that a response is required within 28 days. I do not think my results will be uploaded to the immigration system in time to meet the deadline.

I've uploaded a note explaining the situation and the email from the clinic confirming my appointment as "other documents" on my ImmiAccount, but is there anything else I need to do? Will these be seen? I'm worried about my visa just getting an auto-rejection when I haven't submitted the exams in time. If anyone else has been in this situation, I'd love to know what you did and how it worked out!
