@Qian
Sorry to bother you again I hope you dont mind, my wife just got scheduled for interview and I want to make sure that we don't have any mistakes.
As far as these that you mentioned:
NOTE #4 Offer of Employment, focus on the job description (how the employee’s job is benefiting the US economy), the duration of the overseas post (must be over a year from the time of N-400 filing)
NOTE #5 To show your intention of re-establishing your US residency, you need to write up a statement stating so. Ideally accompanied by supporting documents, such as, US saving accounts, property purchase, pension savings, etc.
Since you said your partner had a home office what did you do for offer of employment like what document Im guessing he was self employed or CEO of a small company similar to our situation?
And also for note #5 did you do that just for the inteview or you submitted it when you filed? We did a letter of intent is that the same ?
Thank you so much
