These questions should be addressed to YC. All I can say is that I have seen founders from just about every country around the world accepted into YC.

Right, apologize about misunderstanding.

My question is in fact is there a chance to request waivers about founders seeking O1 visa that are affected by the recent travel ban on certain countries (with Iranian passport)?

I see. Yes, waivers are possible but the standard for them is high and reports so far are that the vast majority of such requests are being rejected.

Thank you for your answer
