Different POE and temporary address in a different state

[Bill Hamze 89]

So my wife and I are moving forward with the immigration process (IR-1). For now, in the I-130 form, I put in my Texas address as the address we "intend" to move to. Our case is now at NVC. Fees not yet paid, docs not yet submitted.

 

However, we are considering entering the U.S. through a different POE and staying with my mother in a different state for at least a few months. 

 

If we decide to do that, do we change the "intended" address to that of my mom's, and use the household I-864 paperwork? Or should we keep my permanent address as the intended address, use my own I-864 with my mom as a joint sponsor (but not a household member)? My preference would be to keep my tax home the same, instead of switching it back and forth.

 

Once we enter the U.S., we will need to get the social security card, the actual green card, etc. mailed to us. Are there any disadvantages to having these mailed to my permanent address while we actually live at my mom's address? (I'm willing to fly over there to fetch those documents when they arrive and bring them back, or have a relative do it for us.)

 

While this is a long way off, I'm asking now because it might change the way we do the I-864 paperwork.

 

Thoughts? Thanks in advance.
