Over a month ago we sent USCIS( sent it to the same address we sent the i-130 petition) a letter to upgrade my i-130 petition after my husband became a USC. Should I expect a notice from USCIS about the change? or should we have sent the letter to the USCIS service center currently processing our case? Did we do a mistake sending the i130 upgrade to Phoenix,AZ?
i-130 received on 14th January 2019 and is being processed in California Service
i-130 upgrade sent in 15th May 2019 to Phoenix,AZ( where we originally sent the i-130)
