可能我是太高兴，没有说得很清楚，虽然是特殊，现在写明白大家可以参考。
It doesn't matter how long you have been in the business, there are simply things you don't know. Here is all of the information that you need to know.
The visa type I received was a CR-1 which is a conditional IMMIGRANT visa based on family (in this case, as a spouse of a US Citizen). It granted me a permanent residence (green card) upon entry into the United States (delivered to my address in 2 weeks).
The way my hu*****and and I filed our paperwork is considered "direct consular filing" (not an official term). Yes, you absolutely CAN file directly with the embassy in many countries. Read up on it here: http://www.kamya.com/intro/dcf.html. Or here: http://www.visajourney.com/forums/index.php?autocom=custom&page=dcf
Direct consular filing means that the consular officer can approve the I-130 petition (which normally is processed at the immigration office). This means that the I-130 PETITION and the DS-230 APPLICATION are approved at the same place and by the same officer, along with the affidavits and other paperwork.
Filing direct with the consulate ONLY works for CR-1 or IR-1 applications. You can NOT do it with a fiancee or spouse visa class (K classes) as these are NON-IMMIGRANT visas. So if you are not yet married, don't even try to apply with the embassy.
DCF is the fastest way to a visa, and it just so happens to be the best. CR-1 and IR-1's (IR-1 only if you have been married longer than 2 years) are better than the K visas because you do not have to adjust your status when you enter. It is approved as an immigrant visa, which means the PR is immediately granted.
DCF is only recommended if your case is 100% noncomplicated. If you have any criminal records or if your spouse/sponsor does not meet income requirements (per the I-864 affidavit of support), do not even try. If you do not CLEARLY pass, they will not reject you. Instead, they will pass your I-130 to the service center in the United States, and you will have to file through immigration like everyone else. If they do approve you, the visa is granted.
This is a fact, and no matter what you say, the laws and facts are on my side. I suggest you do your research.
We applied the DS-230 Part 1 first (application comes before the petition for many DCF processes). 1 month later, we went in for an interview, and filed the petition and signed the DS-230 Part 2 in front of the consulate. IN THE EMBASSY. I left my passport with the embassy, and received in the mail 1 week later. The GRAND TOTAL of time it took me to receive my CR-1 visa was 5 weeks from the time I sent in my first correspondence to the embassy. I then scheduled a flight to the US. After entry, I got my passport/visa stamped. 2 weeks later, I received my green card. I also received my social security card.
There are many more rules to DCF. If you want to do it, I suggest you contact the country you reside in. All consulates have different rules. DCF is a privilige that US Citizens receive and is not a right. This means that they can refuse you. But if they allow you to process the application this way, it is the easiest and fastest way to do it.
