US Immigration from Philippines

My stepdaughter is in the USA as legal resident from Philippines. Her father is not on the birth certificate and has never had contact with her. We had no problem with her coming here as K2. If I adopt her, will she automatically becomes a citizen? My wife will apply for citizenship next year and our daughter would then become a citizen anyway. I want to adopt her either way and I'm wondering if I should wait until she is a citizen or do it now. In addition, I will be applying for social security while she is still only 11 or 12 years old and I learned that she will receive social security benefits as my minor adopted child, so that's another reason to adopt. Any comments or experience with this would be welcome.

My wife and I have been married for over 4 years. We originally married in Cebu, then moved to the USA several months later. She now feels it's important to get formally married in the USA. I've tried googling if this is actually something that can be done, but came up empty. She claims some of her friends have done it, but is hazy on the details.

Anyone here know if it's actually legal to get formally married in the USA, although I already legally married my wife in the Philippines? Details would be appreciated.

Thanks in advance.

We are now in the USA and need to file a Change of Address so we will receive our Green Cards. Who do I call or write to?

so my noa2 is expiring august 31st. When we got our status ready few weeks ago, the earliest visa interview available was September 7th. so we secured that day for her interview.

What can I do from my end, should I contact manila embassy by phone to have it extended or they do it automatic without me asking?

Thanks....

my son came to the US when he was 11 year old. He was born out of wedlock, but his name is in his birth certificate. The last time he saw his dad was when he was 6 years old. After 16 years of no communication, his dad found him on FB, they started talking and decided he wants to bring him here. His dad has now a family and has 2 kids. Is it possible to bring him here. Also, he has been diagnosed with hepa B.
