For me personally, I am friendly. Ask how their day is, ask how busy it has been, depending on the time of year happy new year ... and small talk about the area.

Last guy I had when coming into the US used to be a software developer as well (Fortran, Cobol, and Pascal) and was interested in what kind of work I was doing.

Haven't had an issue yet. I am on a green card, and even-though all my paperwork is in order I still find myself nervous while waiting to enter the US. Also, the whole fingerprinting/picture taking makes me angry and I feel like I am being treated like a prisoner rather than a tax paying citizen.
