If I were you, I would submit one. You don't want your application to be delayed just because of a document (which is now a lot quicker to obtain). I would apply for a police certificate in the next couple of days and send all proof of it in your letter of explanation along with the eARR. If you hurry up, there is a slight chance that you'll get one by the 14th. If not, you will have one ready in case they ask for it later. In any case, it is always good to have an FBI police certificate for your own record.I have got ITA and my deadline to submit is 14th Feb. I stayed in USA for 2 years and returned back to my country in 2005. Do I still need to apply for PCC from USA as the eAPR does not track addresses earlier than 10 years.
