Grateful Clients

We first hired Katharine in 2020 to assist us with our adjustment of status. We continued to employ her services for my permanent residency and the removal of conditions. Her assistance has been nothing but professional, compassionate, extremely competent and reassuring for me and my wife. It is than...ks to Katharine and Access Immigration LLC that we were successful in acquiring United States Citizenship this month. I highly recommend Katharine to anyone seeking legal counsel pertaining to immigration assistance. We will sincerely, eternally remain grateful to Katharine.

Highly Recommended

I had an excellent experience with Katharine and her team handling my U visa case. The team was incredibly knowledgeable about the U visa process and provided clear, comprehensive guidance throughout each step. What stood out most was their responsiveness and dedication. They took the time to addre...ss all my questions and concerns, ensuring I felt supported and informed at all times. Their meticulous attention to detail and thorough preparation were crucial in navigating the complexities of my case.

The only immigration lawyer I trust

I have known Katharine for many many years, she has represented me twice, once with obtaining my green card and most recently obtaining my citizenship.I cannot imagine working with anybody else, she made both processes as easy and stress free as possible. She genuinely cares about her clients and is ...passionate about what she does. She is absolutely wonderful.

Great Experience

Katharine at access immigration helped us navigate the ever changing and convoluted paperwork and processes of USCIS. She is always organized, responds promptly, and explains processes in advance so we knew what to expect. It was a difficult time for our family personally and we would not have ma...de it through without her support.

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
