Passport requirement
 

Can any UPS Pilot tell me if we require the US passport at UPS, or we are eligible to apply with a foreign passport with the US Permanent Residency (allows work in the US)?
At UPS website says:
Hold a valid passport,
Have authorization to work in the United States

I’m not at UPS but that means a Green scarf.

Yes, Permanent Residency Card is the Green Card.

You can be on PR status but note that it can be a bit of a pain in the rear in general and especially when flying into the US.

Permanent residency (green card) in the US is allowed at UPS and many other airlines just like permanent residency in many EU nations allows American pilots to work in the EU.
As mentioned however, the visa approval process might be somewhat painful if bidding international trips.

All good now. Thank you.
