My Visa will expire in 3 months.
Is there any way I can get emergency extension from NY Chinese Consulate
cause I need to go out of boarder to Canada but re-entry to US requires
validity of passport at lease 6 months beyond admittance. Is that true ?
Anybody knows?
Thanks very much!!!!!! |

Jul 21 expiry has higher implied volatility than its adjacent expiries,
so in theory it is better for premium selling than Jul 14 or Jul 28.
Plus, it is a monthly expiry, so it is more liquid than weekly ones. |

before your passport expiry date.
Your lawyer is probably confused by people with passports from countries
that have agreements with the US to accept passports for return to the
country for 6 months after passport expiry, who can be admitted until the
passport expiry date. For example, India is such a country, but Mainland
China is not. Here is the list: https://fam.state.gov/FAM/09FAM/09FAM040309.

我们学校OIS允许我们OPT EXPIRY前一年内任何时间都可以申请，了解过另一个学校的

那么是不是说，只要学校OIS允许申请了，USCIS都会accept你的opt extension申请？
为什么大家都要设置一个过期前120天的界限？感觉是学校自己人为设置而不是USCIS设

第二买VXX就相当于买SPY扑？大牙都笑掉了，最多正相关吧。VXX基本上可看作vol与
contango的合力作用，put的话分ITM还是OTM，两者都有vol的作用，但要结合expiry啊
，看的是variance，就是vol * sqrt(expiry)，此外ITM PUT还有moneyness的价值。你
