mine is K1

I have some experince about K1 visa.First of all, you have to be married with your hu*****and after you came to the US durning 90 days and also get marriage certificate. You can apply for your socical scuity number at the same time with your passport. After that, you can apply for your conditional green card (expired 2 years) with your hu*****and. you need to download documents from USCIS website then summit them to the USCIS with vaccine infections.After a few months,you will get a letter from USCIS to inform you to be interviewing. You and your hu*****and have to prepare for all the requirment which is list on that letter.If you pass that interviewing, you will get the conditional green card by mail. one year and nine months later, you need to summit your application to remove your conditional green card to permanant green card. two years and nine months after your get your conditional green card, you can apply for your american citizen. One more thing, donot divorce with your hu*****and during those time, otherwise, you will be illeagal in the US
good luck
