What is the best time to apply green card for my mom who is in the USA now
My parents visited us (B2 visa) from China two months ago. I am US citizen. Their legal staying period is 6 month. Now my mom decided to live with us forever while my daddy still wanted to go back to China. So my question is: can I apply green card for my mom now (about 3.5 months left of their 6-month staying period)? Or do I need to wait at least one or two months later to apply for her since my friends told me that it is better to apply until one or two months of 6-month staying period left?
Thank you so much!
