Common Adjustment of Status Mistakes

Every year, I sit across from tearful clients who made simple but costly did some adjustment of status mistakes in applications. These aren’t just paperwork errors—they’re life-altering missteps that can separate families and destroy dreams that were years in the making.
I’m Matthew Peterson, an immigration attorney in Boston, and I’ve seen firsthand how the path to a green card can be derailed by avoidable mistakes. Let me walk you through the five most common errors that could cost you everything.

What Is Adjustment of Status?

Before diving in, let’s clarify what’s at stake. Adjustment of status (Form I-485) is the process that allows you to obtain a green card while staying in the United States. It’s the difference between building your life here uninterrupted versus potentially leaving the country for months or even years during processing.

Mistake #1: Missing or Incomplete I-864 Affidavit of Support

The I-864 isn’t just another form—it’s a legally binding contract where someone (usually a family member) promises the government they’ll financially support you. Without this crucial document and its supporting evidence:

Your application can be rejected outright
USCIS might keep your filing fees (thousands of dollars)
You’ll face significant delays reapplying

Many applicants don’t realize that sponsors need to provide tax returns, employment verification, and meet specific income requirements. One missing document can send you back to square one.

Mistake #2: Insufficient Marriage Evidence

For marriage-based green cards, USCIS officers are trained to spot fraudulent relationships. If you don’t provide compelling evidence that your marriage is genuine, you’re starting your immigration journey under a cloud of suspicion.
Strong evidence includes:

Joint financial accounts and responsibilities
Shared lease or mortgage documents
Photos together over time (not just your wedding day)
Communication history before and during your relationship
Affidavits from friends and family who know you as a couple

Weak evidence now often leads to difficult interviews and potential denials later.

Mistake #3: Incorrect Filing Fees

USCIS seems to intentionally complicate fee structures, and they change frequently. In 2023-2024 alone, we’ve seen multiple fee adjustments that confused even experienced practitioners. The consequences of incorrect payment are severe:

Immediate rejection and return of your application
Lost processing time (often 3-6 months)
Potential changes in circumstances that could affect eligibility

What makes this particularly challenging is that different forms have different fees, and some can be bundled while others cannot. The exact amount depends on your age, status, and which forms you’re filing together.

Mistake #4: Missing Required Evidence

USCIS instructions often span dozens of pages with document requirements buried in dense text. Miss just one required item, and you’ll face:

Requests for Evidence (RFEs) that delay your case by months
Potential denial if you can’t provide the missing document in time
Extra costs to overnight materials or expedite processing

Common missing documents include birth certificates with certified translations, prior immigration documents, or medical examinations (Form I-693) prepared by approved civil surgeons.

Mistake #5: Applying When You Don't Qualify

Perhaps the most devastating mistake is applying when you’re fundamentally ineligible. The rules around eligibility are complex and filled with exceptions and special provisions.

For example:

If you entered without inspection, you generally can’t adjust status (with some exceptions like 245(i) provisions)
Certain criminal convictions can make you inadmissible
Previous immigration violations may trigger bars to reentry
Unlawful presence can create 3-year, 10-year, or permanent bars

The consequences here go beyond simple rejection—you could face removal proceedings and permanent bars to returning to the United States.

The Value of Professional Immigration Help

When the stakes include your family’s future and your ability to build a life in America, professional guidance isn’t a luxury—it’s a necessity. An experienced immigration attorney can:

Identify potential issues before filing
Ensure all forms are correctly completed
Gather and organize proper supporting evidence
Calculate exact filing fees
Prepare you for interviews and respond to government inquiries
Apply for work authorization and travel documents while you wait

At the Law Office of Matthew Peterson, we help people navigate the complex immigration system not just in Boston, but nationwide. Many clients come to us after attempting DIY applications, and almost all wish they had sought help from the beginning.

Taking the First Step

Not everyone needs full legal representation for their immigration journey. That’s why we offer consultations to assess your situation and determine whether your case requires attorney assistance.

Remember, immigration isn’t just paperwork—it’s the foundation of your future in the United States. While filing fees and attorney costs may seem expensive, they pale in comparison to the cost of mistakes: years of separation, lost opportunities, and sometimes permanent consequences.
