Pros
If you start of scratch in usa, its ok, Svam is a good sponsor , them have a lot of contacts with a many middleman's, you can find a work quickly, svam provide the support to live a while in a guesthouse, I think, that is the only one company that do that, so that is a good point. The challenge come after that you find out a work, the process to find a word can taken, 1 months up to 3 months. they sponsor the visa and give you insurance.
Cons
svam, is not the only option in usa , They are only a sponsor more that exist in states , and them are working with a schema of layers, so your salary is split into different middleman , so if you have only one middleman or if you work directly, your salary can be better. You need consider the balance the process of a green card, take time, at least more that 2 years .... so try to handle a good wage, take a look the salary that is pay in each state, in order to have a idea. Usa is expensive so for example a rent is between 800 to 1000 thousand dollars and the food and transportation like 600 more, so your salary is affected. The medical services are very expensive, try to have a dental service added in your insurance
