回複：體檢(I-693)有效期是一年嗎?

theoretically, i-693 is valide for one year. However, due to backlog in case processing (which means it often takes more than one year to process an 485 application), ins adopts a policy that extends the validity of i693 to the time a decision on the 485 application is made, if i693 is filed with 485. That is to say, you don't need another physical examination if u submit 693 at the time of 485 application, no matter how long the case processing time is.
