I'm about to apply for a Workcation DTV from the Los Angeles Consulate. I have all of my documents together. My question is should I create one large pdf of all of the documents together to submit everything at once or do I submit each document separately? i.e. passport biodata page, driver's license, employment certification and 6 months of bank statements. Thanks.

Might seem like a daft question, I have a 6 month multi entry visa, got stamped in for 60 days a few weeks ago, but have decided to head to Cambodia for ten days or so then come back, is there anything I should be doing at airport visa wise before I leave or simply show them my multi entry when I get back and get stamped in for 60 days again? Thanks

Does O visa require health insurance?
