Hello, recently I switched from H4/EAD to H1B, but have an unexpired H4 visa that I got from last stamping. and my spouse switched from H1B to H4 and she has an expired H1B visa (less than 1 year) When we travel to India, are we eligible for drop box considering the 1 year rule? Or the COS scenarios makes us ineligible for dropbox? We were also thinking if this is allowed in Mexico for stamping?
