My son shipped out last night and I received the call around 1:44 am. I am anxious to receive the formal letter with the PIR date so that I can get busy making arrangements. I have 3 important family members that want to attend in addition to me, dad and my other son. I hear that they will only allow 3-4 guest max. Today is a day of no sleep for me. I am one worried Mom!
My son's recruiter gave my son's PIR and mailing address 1 week after he arrived. I received the formal letter about 2 weeks after.
Please keep in mind that the address the recruiter provides might not be the correct address.
There are various reasons why the address can change so it's safest to wait until you receive the official letter before sending off your letters. Go ahead and start writing letters now (# them in the bottom corner so your SR knows what order to open them in) and then as soon as you get the address you can drop them all in the mail.
