Roam Around USA in 30 days - my own experiences with my 6 years old son.
Steps I followed for my plan to "Roam Around USA" were: Just two months before the planned date to visit and roam around USA, I contacted a travel agency for the USA visa registration purpose. In the meantime I had to collect many important documents. Since I was visiting to my brother's place, he had to give me certain important documents from his end also. Currently, being dependent on my husband financially and also having a minor child, according to the USA rule, my husband had to give his supporting documents as well as a consent letter. With all the correct documents, it took hardly 10 days to get the appointment for the bio-metric round, the first official step towards my vacation plan to travel around USA in 30 days. The next day was the visa interview round at the USA Embassy. He had to take off from his school on that day.
