Hi, I have H4 visa valid till Dec 2016, my husband's H1 is not stamped in the last 3 years. Now he got H1 extension valid till 2019, H4 extension is in process and I plan to travel to India in Nov 2016. Can I travel with H4 extension pending? Am I eligible for H4 DropBox facility or need to take Visa Stamping Interview at the Consulate? Thanks.
