This is an example of chain immigration. Where a child of a US citizen gains citizenship from a naturalized citizen. It is not as simple as you might think. It is not automatic. Same evidence proof, background checks, fbi investigation, fingerprint checks as any other applicant. It is a long and involved process and it's cost is near $2000 for the application. This application took over a year to complete..total mom and daughter path to citizenship is 8 years and thousands in costs. Look at those smiles...well worth the wait.
