I applied for my and wife's app on Feb 27th simultaneously (US PR). She got Cond. App. on 10th April. I am still waiting (57 business days/80 calendar days).

She has been to 2 non-NAFTA countries in 5 years while I have been to 1.

I have visited Canada few times in 2014 while she has never stepped foot there, so is CBSA taking long to analyze my Canadian visits?

I have a hunch a batch of applications around Feb 20th-March 1st are inexplicably stuck somewhere (with nothing to do about applicant specifics).

GOES FAQ's still mention 4 to 6 weeks to process applications which I am well past.

I plan to start making calls and sending emails to CBP + CBSA starting May 24th when I complete 60 business days.

I will send an email here https://help.cbp.gov/app/ask

and then make calls to the helpline numbers:
800-842-7647 for CBSA & 855-USE-GOES for GOES
