Step 1: 我刚刚网上给父母分别提交了I-130。 信用卡支付了费用。他们人在中国，所以是境外申请。

请问下一步就是等待吗？ 有朋友建议concurrent filling I-485，但是I-130在线表格首页就有说："You cannot filr Form I-485 or Form I-129F online at this time. Please see our Form I-485 and Form I-129F webpages for current filing information, and refer to the form instructions for specific instructions on completing each of these forms. Only forms properly filed can be receipted and adjudicted. Any Form I-485 or I-129F included as supporting evidence for your Form I-130 cannot be receipted or adjudicated."

如果目前能做的就是等待I-130被批，那大概是要等多久呢？这是要等待时间最长的一个，对吗？

Step 2: 我理解I-130被批之后，要交I-260 (Immigrant Visa Electronic Application)以及I-864 (Affidavit of Support Under Section 213A of the INA)? 这些现在是不能交的，只能等待，对吗？

Step 3: 下面一步是父母体检、面试，对吗？

Step 4: 是到这里officially才可以交I-485 (Application to Register Permanent Residence or Adjust Status)吗？

非常非常感谢！ 我把这条路走通了，一定来板上发流程总结，造福后人！
