I don't have an I94. I came here as a child in July 1999. But record of my stay starts in August 1999 on my immunization record. And I have record of continuous schooling/immunization documents since September 1999 to now. Would these suffice and be adequate substitution for I94?

Also my dad has been paying taxes since he came here in 1995. My mom, my brother, and I came 4 years later in 1999, but our names show up on my dad's taxes starting 2004. Should I submit these forms as well? I am little paranoid that CSCIS may say something about my dad not putting our names on his taxes until '04.

And as for proof of our stay here on June 15th, I did go to a post office to have my presence notarized, but they didn't have a notary. Instead USPS stamped June 15th date on my self-made notary paper. Is that okay? I do also have financial records from my two different bank accounts of money spent on June 15th, but they were both online purchases.

Sorry for the long read, just want to make sure I am doing this right!
