Thanks LucyMO. I have been searching here as well as internet for the following info. I hope you don't mind to help answering following questions as well....
After I do a search for info from this forum, I have few questions...
1. Someone mentioned I-130 should be printed on yellow paper. Is this required just for concurrent I485/I130 filing only? For my case, I am filing I130 only.
2. Is it true all the supporting document, including my sister's birth cert. is not required a notarized copy?
Thanks in advance for your prompt response.
