Could you please update here on how you are proceeding here and what their response if you contacted them via email or phone call.
My tracker got updated on August 10th, with the message that our Oath will be on September 11th, but didn't received the oath invitation letter yet. So, preparing myself to followup if we don't receive the invitation for some more time.
Others, how long does it generally takes to receive the Oath invitation letter after the tracker was updated with Oath date. Did anyone else here was in the same boat, i.e the didn't receive the letter until very close to the oath date and what was the steps to follow to resolve the situation.
