The whole visa issue is such a needle in a hay stack unless you have immediate family sponsorship in the US. So many organisations just will not go through with the complicated process of applying for a visa.. But its not impossible.. I myself am in a similar situation... The US immigration needs such an overhaul and the good guys with great intentions to come to this fine country are the ones who pay for it.. Yes, things are not what they used to be but it is still a good place to be.. So even though there is alot of truth said here about the grass not being greener on the other side, if you want to make it work, you can do it. Im still trying and hoping that I can !
