1. Thanks for the heads up about the Mobile App not being available for LPR. I saw that Canadians could use it (my spouse), but I didn't read carefully that it is only for Canadian visitors.
2. An LPR I know went through SFO on Saturday and said that they were asking LPRs to go in the Visitors line, not US resident line - different than usual. Unclear if this is a one-off, or a long term change. That's what triggered this line of inquiry.
