I-485 Part 8, #63b and Part 2, #3 (H1B visa)

[Bezalel 0]

I'm concurrently filing I-130 and I-485 to change from H1B to permanent resident through marriage.

 

For Part 8, #63b is should I answer "No" if I answered "Yes" in #63a? Or leave it blank? #63a reads "Have you EVER failed or refused to attend or to remain in attendance at any removal proceeding filed against you on or after April 1, 1997?" #63b reads "If you answered to Item Number 63.a is "Yes," do you believe you had reasonable cause?

 

For Part 2, #3 - I'm an H1B visa holder (approved Oct 2016). Do I put my H1B receipt number on my I-797? (The one that starts with EAC, WAC, etc.)

 

For all applications, the instructions say not to leave anything blank so I'll be writing "N/A." But should I write "N/A" for questions that include the phrase "if any"? For example, I'm currently married and have no previous marriages. For I-485, there is a section "Information About Prior Marriages (if any)." Should I leave this section blank or write "N/A" for all blanks?

 

Thank you!
