approx. six months.
You can travel within the US with a green card so long as it is valid. A green card is NOT a valid document for international travel outside the US. To travel outside the US, you will need a passport and possibly visas depending upon the passport you hold and the country you visit. Please check with the local embassy/consulate for the most up to date visa requirements for your country's passport prior to travel.
How long a person with green card can stay out side US if he is a United Nation employee?
you have to be in the Unied state for 5years or get married with a u.s citizen for 3years.
I dunno, how quick can you fill out forms, and how fast can your preacher talk? Whether you have a green card or not is largely irrelevant to how long it takes to get married.
90days
yes, bout a month???
Years. But if you let that tourist visa expire and you are still in the country, you will never get the green card. Keep your visa current!
well there is 365 days in a year so if you add a green card the year would have 372 days in a year. and that's a kick in the butt to figure out.
Never
i think so, u can get married whenever u want
A Green Card is issued for a 10 years period. You can keep on renewing it as long as you want. So there is no limitation on how long you can continuously in USA with a green card.
The issue really is one of whether you intend to maintain permanent residence (PR) in the US. Often this depends more on how long you stay outside the US that anything else.

I strongly recommend getting a re-entry permit if you will be living outside the US for more than 6 months.
