Hi,
My sister had her interview with her family in Oct 2019 and right after the interview they called my sister and told her that Embassy is ready to issue visas to my sister and kids but not her husband as it requires more time but sister declined and wanted her husband to be included in their visas and they put their case on administrative processing, we sent out many messages to Embassy but they gave us the same answer (administrative processing) and its been more than 3 years since interview and when we contacted the Senator, we got a message from Embassy to give them 30 days and then to follow up and after 30 days they gave another message of administrative processing, is this a good time to file Writ of Mandamus? Thank you.
