&gt; Some friends have recommended the Visa Waiver program, but this case does not appear in the allowed travel purposes.<p>You&#x27;re right - the Visa Waiver program is not right for working in the US.<p>If you can get an American company to sponsor an H1-B visa, that is one option. You will be restricted to working for that firm alone.<p>If you have exceptional ability in your field, and you can convince an agent to sponsor you on this basis, you could qualify for the O Visa.<p>If you become a college student in America via the F-1 visa, you can work part-time (up to 20 hours per week). No restriction on companies you can work for.<p>If you get a Green Card via the annual Diversity Visa Lottery or through marriage to an American citizen, you can set up as a consultant (self-employed) and work for multiple companies.<p>In short, there is no quick and dirty way for you to work onsite for an American client.
