Hi, I am traveling from MNL to EWR with a 6-hour layover in Shanghai Pudong Airport.

I have been seeing older comments that I would need to claim my baggage and re-check in my baggage to transfer for my flight to EWR from PVG. Is this is still the procedure?

My itinerary:
MNL to PVG via China Eastern
PVG to EWR via United Airlines

In addition to above question, do I need to secure a transfer visa?

Thanks!
