21. Today I am grateful for the DS customer service guy I spoke with yesterday. I have been diligently calling to check my clearance status every 2 weeks since September, only to be told every time that it's "under investigation" and not one word more. The target completion date has passed. Finally, today, the guy I spoke with said that he wasn't seeing what he expected to see for how long my case has been in the works and "not for me" (he was very clear about that) but for his own curiosity he's getting in touch with my case manager to see if something's up. He promised to call me within 24 hours with any information that he can tell me. It may be nothing but at least someone is actually looking into it!
