I have a Green Card since 2000; I have to attend to family matter overseas which requires me to spend long time over 3 years. I'm married to a US citizen whom with me now over seas. I would like to just visit the USA; I'm not planning to reside in the US yet, should I apply for a tourist visa at the US consult. I have applied for a travel document last year while I was in the US, but t I got no response from them
