Can my US citizen step daugther file for me and her dad at the same time? 9 Answers as of September 24, 2011

If you married her mother before she turned 18 and still maintain step father/child relationship, she may petition you and or her biological father.

Yes, possibly. Your marriage must have occurred prior to her 18th birthday.

In order for your stepdaughter to petition for you, the step relationship had to be created before she turned 18. If the marriage that created the step relationship existed before she turned 18, then she can petition for both of you.

A U.S. citizen can petition for his/her parent and step-parent. The petition can be filed at the same time if the step-parent relationship was formed before the step-daughter reached the age of 18 and the marriage between the parent and step-parent is bona fide. The only issue may be if you have sufficient income to support both her parent and step-parent.

Generally, a U.S. Citizen child who has reached age 21 may petition for her parent and step-parent to adjust status to become Lawful Permanent Residents (to get "Green Cards"). Separate petitions for each may be filed at the same time. There are other details that need to be assessed in order to confirm legal eligibility, however, and it would be wise to consult with an immigration attorney.

Yes she can. The process will depend on your manner of entry into the US in general. If you came with a visa, then file an I-485 packet. If not, then start with an I-130 and wait for it to be approved and go from there. If you are the beneficiary of 245i under the Life Act, then file an I-485 packet and pay the fine. There are many variations of this. The point I should make I guess is that if this is something that is important to you and your family, then hire an attorney who can sort all this out for you and make sure you will get the benefit of your bargain. We can help. Good luck!

Maybe but depends when you got married to her father. If she was over the 18 of eighteen at the time of your marriage, then the answer is no. In such a case, she could only file for her natural parent (provided that the parent entered the US legallly).

If you were married prior to your step-daughter's 18th birthday, then she can file on your behalf as well.

If you married her mother before her 18th birthday, she can apply both you and her biological father.
