Does having another getting in the neighborhood make you perversely *more* aware of your minority status? As a woman I felt that on occasion when I went from being the only woman in the working group to one of two. It was weird, but I might be weird. :-)
No. There was a man from France in our HOA. I don't know if he is still here. And I think there were some Canadians living within our HOA a few years ago. Possibly they rented and were here temporarily. Being an Alien here isn't a problem. We have all the rights a Colombian Citizen does, with the exception of being able to vote and serve in the military. I suspect getting a government job would be tough for an Alien too. I've had a Residence Visa since 1994. I am welcome wherever I go.
Sometimes I will go into a tiny little store or a bakery to buy something and I know that I may be the first North American they have ever met and I think they are really happy to have me for a customer. And, I remember, for years, if there was an issue, my wife would send me to get the issue resolved, because she felt they would bend over backwards to help an American, and that they would not give her, a Colombian woman, the same help, and certainly without any enthusiasm.
I don't know what kind of work you did. I was a Software Engineering Consultant. My memory has about 20% of my coworkers were women. I can remember 3 of them by name. I occasionally communicate with one of them. (Spin off from the NK thread: We worked on 2 systems that were deployed in South Korea. I remember one morning getting into the office and answering the phone and leaving her a note that they needed her in South Korea. She solved their issue without going over there...) One woman I worked with her and her DH, she was really sharp. She worked on "temporary" job assignments in places longer than some of their "permanent" employees did and she was retained (to her surprise) when they were letting "permanent" people go.
If my DD decides on a STEM career, I would discourage her from something like Petroleum Engineering, but the girlfriend I had before my wife is a Chemical Engineer and I know another woman who is a Chemical Engineer.
In something having to do with Computers, I think women do OK, but I'm not a woman, so I don't know how that works in a workplace environment. The older DD of a friend in majoring in Computer Engineering and dual majoring in something else, that I can't remember at this time.
I think a lot of that would have to do with the actual place one is working in. Three of the places where I worked with women were Government Contractors and we just tried to get the stuff to work properly and ASAP. I remember at one of those places, a young Engineer (Hardware) was assigned to work with the Engineer who designed the Hardware I was working with. I felt sorry for her, because he was the only incompetent Hardware Engineer I ever worked with. The Software Group ended up redesigning that Hardware.
Along the same lines, if I was the only man in a group of 10 women, I would probably feel odd, so I can easily see how that would work.
Avianca, our largest airline, 2 or 3 years ago, on International Womens Day, sent a jumbo jet, with an all female crew (Pilots, Relief Pilots, Flight Attendants, etc.) from Bogota to Spain and back to Bogota. I think it took months for the Crew Schedulers to get that worked out... So, no, it isn't every day that your Pilots in a Trans Atlantic Jet are both women, but a lot of positions are open to women now that were not to a previous generation of women. As the father of a DD, I think that's great.
