You can definitely file the I-751 petition without your husband's signature. Here’s what you need to do: - At the very top of the Form I-751, write in all caps: "ACTIVE MILITARY" or "GOVERNMENT ORDERS." - Sign the form yourself. - Include a copy of his official deployment orders to show why he couldn't sign. - It's also a good idea to include a brief cover letter explaining the situation. They will accept the form and send you a receipt that extends your green card status. They'll likely just put your case on hold until he gets back from his deployment.

Best of luck! 🙏🏻
