"我是个学生。我们这儿有个clinic，按病人的收入收费。我可以申请较低收费标准。这样的话，看个小病也不要很多钱。
我现在的保险不太好。我准备不买了，因为我要自己掏钱，而且这个保险cover的很少。我计划万一有个什么病痛就去这个clinic，算下来比买保险还要省些。就是不知道以后办绿卡，这些记录会不会有什么不好的影响？"
Thank you for your reply. But I am not sure about the differene between Cash福利and 暂时帮助性质. Could you explain more to me?
The clinic charges acording to the income of patients. They will check their income when they go there to decide how much percent of their medical expense they should pay. I have been there once. They have my SSN.
Could you descide for me what type this aid is? Thank you for your help!
