l****z 发帖数: 29846 | 3 Pro-Life Family No Longer Forced to Pay Obamacare 'Abortion Surcharge'
via Breitbart Feed
When a pro-life family in Connecticut found that their state Obamacare
exchange only offered plans that included abortion coverage, they filed a
lawsuit against federal and state officials because they could not purchase
a plan that did not require its participants to pay for the elective
abortions of others. Last month, the Bracy Family dismissed its lawsuit
after the addition of health plans to the exchan... 阅读全帖 |

这种车迈数是不是不靠谱啊?另外 有事故的车不敢买?
谢谢各位 |

S***P 发帖数: 335 | 7 说说我这的情况
刚买房,贷了$417,000, rate 3.75% (30 year), 一个月付$1931(不含proprtty tax
and i
nsurance)
现在refin的话, 还是30年, no cost rate 3.625% (closing cost 不计入loan a
mount), 月付$1901
一个月少$30, 真不值得做吗? |

S*********s 发帖数: 416 | 9 非常感谢你的信息!我的保险公司说是因为听力不包在保险里面,保险是ppo的,不是
因为out of network的问题。只知道另外还有dental,vision的险,看了公司的条款
,也没有明确说听力包还是不包,但是我觉得听力的测试应该是属于medical的险的啊
。她们没有告诉我可以appeal,看来我可以要求appeal一下。
实在不行再问下测听力的看能不能打折。上次因为医院没给听力公司Insurance的信息
,还收到他们的一封信,说不付要送collector。 |

SHUFE and SWUFE does not pay full stipend to Hai Gui, which means you only g

2010年-2011年两年而已,一会看见你说你找博士后找不到,一会见你说物理PHD读了
一年半打算quit,一会见你说要去休士顿读地球物理硕士,一会你又要学石油以后找油
公司的工作,一会又见你说去读数学金融硕士了,一会你又问想找quant工作现在
学C++如何,一会又见你问现在是统计硕士该怎么考SAS找工作,一会你又问选生统还是统
