I am not so sure but most likely the same site. ustaveldocs.com.ph is what I've always used. Doesn't your 221g mention any info on how to contact them? I have never seen a 221g, so I've no idea what it contains or how it's formatted but it's for sure standard procedure and pretty straightforward. Escalation of case only means bringing it up to the next level up which requires a follow-up. Stay the course of following up and ensure you do what your 221g says. These things require patience. Be patient and conform with what the US Embassy requires. Good luck.
