US Immigration from China

That's all. You're all providing such an amazing service and I love how supportive this community is. Great job everyone.

Hello, just had a few questions regarding the I-130 form. I am submitting it online, and was wondering for the documents that ask for a document with the spouse's name/address in his/her "written language" - does this just mean in their foreign language, or does it mean that the name and address must be written out and then scanned in. Basically - are typed forms okay?

Similarly, for letters of Affidavit, do those have to be written out as well? Or is a typed form okay.

On the immigration part, it asks for a I-94 arrival departure record number - this is asking for a current I-94 number correct? My spouse had one in the past, but it expired like 2 years ago. Do I need to put that information on the form?

Lastly, the secondary evidence stuff is optional correct? There is one area for a letter of admissions from a school. If I (the benefactor) am in school, should I provide a letter for my admission? Or is that mostly evidence for children or something.

Thank you

Form DS-260 asks for the petitioner's phone number and only accepts US formats. What if the petitioner lives abroad and doesn't have a US phone number? Should they give a family member's number in the US?

Should I add a joint sponsor to my case just as insurance? Or am I OK to file without one? Thanks!
