We have so many stories on this forum on PA delays, they can't be counted.
PA is the worst state for processing claims, especially those that require any kind of documentation or review.
An ordinary claim shouldn't take six weeks. But, if your former employer has lagged in returning info to PA, if your claim requires a review for one reason or another, or PA doesn't have current wage info for you, it can take a looooong time.
You had better try to find out what the holdup is. Also, suggest you email all your state legislators on this. Six weeks is too long for any claimant to wait. We have several reports of instant action (within a week) when claimants have contacted their state representatives.
