You have 6 months from the date your immigrant visa was issued by the Embassy to enter the US. The expiration date of your visa is indicated on the visa itself (“IV Expires On …”).
Upon your arrival in the US, your visa will be stamped. This stamp, along with the visa itself, will serve as a temporary green card for the 1-year period following the date of your arrival in the US.
I hope this clarifies things for you.
