My uncle's petition has been DQ'd since April 2021, up until now we still have not received any notice of any updates such as interview date. We have contacted NVC many times and we get the same response, COVID and staff shortage. My mom, my stepdad and my grandma (who is my uncle's petitioner, a green card holder) will travel to the Philippines to spend Christmas with him. Should they make an appointment at the embassy there while visiting? What's the best way to approach this? We just don't know if we should make an appointment or just keep on waiting. I feel like his case got put in the back burner and need a nudge. Any input will be greatly appreciated.
