When some shows are filming

[Dunphy]

Hey I'm planning on writing to some actors on some shows but was wondering on when the shows are filming. I have the address to most of them but don't want to be sending them out if the stars wont be there. So any help on if they are currently filming or when it is expected they will be filming would be great. The shows are:
-Sons of Anarchy
-Community
-How I Met your Mother
-Two Broke Girls
-Modern Family
-Arrow
-Switched At Birth

Arrow finishes this week. That's all I know.
