תאריכי כניסה לארה''ב

Hi F, Thank you for your message. To answer your question, you must enter the US BEFORE your visa expires. Usually, an immigrant visa is valid for 6 months. Therefore, you usually have 6 months to enter the US once your visa is issued. However, sometimes the validity of your visa is shortened because of the expiration of certain documentation, such as medical exams. For example, if you medical results will expire in two months from the day your visa is issued, then it is possible that your visa will only be valid for 2 months. This decision is made by the Consular Officer, and the expiration date is listed on the visa itself. Therefore, it is very important to check the expiration date as soon as you get the visa, and it is also recommended to only complete the medical exam about 2-4 weeks before the interview. I hope this helps. Good luck. -Mike
