This is a first-fall Lesser Snow Goose. The dark on the crown and nape are more pronounced than usual, but otherwise it is pretty typical. The bill shape, including gape, and the bill and foot colors are all typical, although they should change over the next few weeks.
A domestic goose derivative should have longer bill without the gaping gape, a longer and thicker neck, and likely a more pendulous butt.
Young of arctic geese often can be very approachable when they arrive in the lower 48.

Subject: [obol] Odd goose at Arlington
Stopped for a potty break in Arlington on our way from east to west and saw this odd goose... The two mallards that were with it seemed very used to people being around, but I haven’t been aware of any domestic waterfowl in the area. The goose was making an occasional soft whistling noise and feeding on the grass near two male mallards.
