Question

My father-in-law was given a 221-G (pink form) for Visitor visa (B2) in chennai consulate. Whereas my mother-in-law was given a visa.

The PDF avl. in chennai consulate says the status of my FIL as "Pending process". He took his interview 10 days back.

Let me know how much time does it take for the consulate to respond to a 221G case?

Answer 1

221(g)

Applicants are ineligible under section 221(g) because the applicant failed to bring some information or document, or some further procedure or review by our office or another U.S. government agency must be completed.

Please follow these instructions for a 221(g) refusal:

1.If you have been requested to wait until the Consulate contacts you, please do not make an appointment. Your case requires further administrative processing and the Consulate will contact you once this has been completed.

2.If you have applied in Chennai and were issued a 221(g) letter and asked to come back when you are prepared with all the required documents, please do not make an appointment. You may appear at the Consulate on any working Tuesday, Wednesday, or Thursday in the morning (between 10:00 and 12:00). If your visa was not issued under section 221(g), you are required to fill out a new application form when you reapply.

3. If your visa was denied under section 221(g) at the U.S. Embassy in New Delhi, or the Consulates General in Mumbai or Kolkatta, and you are instructed to reapply in Chennai, you must complete the following steps to be seen for an interview in Chennai.
