In reply to Nicole Suddard :
I don't know a ton, but I do know that in my own employment history, networking/personal connections have been the leg up that made the difference every time I was reaching or pivoting in terms of work, even when I was relocating or going out on a limb. It is really easy to fall into the "I don't know anyone" trap, but most of us are more connected than we realize.
Since she is making a move, she may not have a ton of connections yet, but all is not lost. You never know who might help open the door.
I'd recommend she list all organizations she is or was connected to in the past. Alumni office from her alma mater, church, service clubs, volunteer organizations, sorority, hobby/special-interest clubs, professional organizations, I don't know what she is into, but Master Gardeners, Elks Club, 4-H, Society of Germans from Russia, Facebook groups/online forums, Honda N600 owners club, or whatever...they may have a local branch in DC, or provide an avenue to alert members she is new to the area and looking for opportunities. Follow up with as many on the list as possible.
I'd also recommend she make a list of all individuals she has some connection to in the DC area, extended family, former co-workers/classmates, new nextdoor neighbors, connections her partner has, etc. After a brainstorming session of just listing them all, at least some of these connections might be eliminated as impractical/awkward, but I have found the exercise to be useful, and it generates a list of people to reach out to regarding her interest in hearing about opportunities they might stumble across or hear about.
