That statement on the website is not gospel.
We just had a report from a NJ claimant who did not have 18 months employment in NJ and received benefits from NJ. First quarter of her base-year she worked in FL. NJ opened the claim anyway without the FL earnings and paid state benefits on that claim. When she realized she didn't qualify for EUC, she went back to NJ to include the FL earnings so she could receive federal benefits. She just had her monetary interview for the purpsoe of recalculating this claim.

Have you applied in NJ, as yet?
If not, get the ball rolling - file a claim with NJ online or go to one of their offices. PA will ask you to do that, anyway, because the NJ employer is the employer which laid you off.
If you get a denial from NJ, then go back to PA with that denial. You are entitled to benefits. You just need to be very proactive in getting this claim established.
Also, fyi, interstate or combined claims in your area are very common. You might even qualify for commuter status as a NJ claimant. There are many nuances to unemployment benefits.
