Yes I have to be in the US by April 20, since my medical result will expiry by then. The final sputum result with the Xray after treatment is only valid 3 months; hence, April 20. If I don’t make it, I will have to the medical again and be delayed for another 4 months, coz they’re getting another sputum sample again (yes, it resets and not consider my latest sputum result). And then, once I have it, wait for the embassy to process things and hopefully make it to the 3 months validity. If not, I might redo everything again and another 4 months of delay.
