I need help on my situation. I applied for a visitor visa to the US. When I filled in my application, I requested a month and I was given a 2-year multiple entry visa.
I know that, at the port of entry, it's the immigration officer that determines one's stay. I now want to stay for 4 months, if the officer gives me 6 months when I enter. I don't plan to overstay and ruin my future travel chances.
What should I do to not ruin my chances, but still stay for 4 months? Can I book a return for one month then, later, extend it to 4 months?
If I stay for 4 months, won't they think I am not truthful the next time I apply for a visa?
