NNU Immigration Limited was founded by Nita Nicole Upadhye in 2012 and since its inception it has maintained an unwavering commitment to providing the highest level of service to clients seeking bespoke immigration advice. Our team of three highly-qualified lawyers and support staff is extremely responsive, knowledgeable and supportive of our clients and their personal and professional goals. All of our lawyers have transatlantic experience, having worked for law firms in the United States and United Kingdom. The principal attorney, Nita Nicole Upadhye, has been recognized in the International Who’s Who of Corporate Immigration lawyers, and is the former President of the American Women Lawyers in London (AWLL) and the former Chair of the Rome District Chapter of the American Immigration Lawyers Association (AILA). Please read more about our Team.
We will typically speak with you on the phone briefly to understand your circumstances and determine if this is something we can properly assist with. Some clients need a discrete piece of advice for which a consultation meeting is necessary, but no further action thereafter may be needed.  Other clients may have an issue that we are unable to assist with (for example, their criminal waiver application has been pending for several months at the CBP Admissibility Review Office and they are seeking our help in speeding up the review process) and for yet other clients, we can determine quite quickly that this is a matter we can assist with.
Our business hours are 9 am to 5:30 pm Monday through Friday. However, please feel free to call or email us after hours. We are committed to returning our client’s and potential client’s calls and emails within 24 hours or less. Please contact us through our Contact page.
Yes, our lawyers have spent years honing their qualifications and experience in this area of law and in order to properly advise you of the legal options available to you we will charge a fee for a consultation meeting. Should a meeting be necessary we will advise you on the consultation charges prior to booking a consultation appointment.
We are committed to providing you with the most cost-effective legal representation. We typically arrange flat-fee agreements and will provide a fee quotation once we have assessed your circumstances and understand the level of expertise and time commitment involved in carrying out our services. Our fees reflect our strong reputation, skill level, expertise and years of experience. If you are seeking the lowest fees we are not the best fit for you. If you are seeking the best representation for your application then you will want to consider our firm.
In exchange for our attorney’s fee, your case will receive the professional attention of NNU Immigration attorneys, all of whom are experienced in handling your application through all stages of your application: from the assessment and information-gathering stage to the analysis and strategy-formation stage; to the preparation and advisory stage to the final decision on your application. Our mission is to provide our clients with the most efficient legal services possible, collaborating with our clients each step of the way. You can expect to have a dedicated lawyer to guide you through the application process, applying our knowledge of immigration law and local guidelines, our unique legal strengths, our ability to effectively advocate difficult and complex cases, and our desire to work cooperatively and ethically to attain favorable results for our clients.
Please call us at +44 208 004 3492 and speak with a member of our staff who will have a brief discussion with you to determine if we can assist you.
We want you to trust that we are here to help you navigate the process of obtaining a visa as smoothly as possible. We expect our clients to be honest and responsive so that we can best prepare your application within the optimal timeframe. The preparation process is collaborative, and we are unable to adequately present your application without full knowledge of your circumstances and your full cooperation.
We will keep you informed as to any important milestones in your case so that you are always up-to-date. We are here to support you and take some stress away by keeping track of all of the detailed proceedings on a day-to-day basis.
The length of time that this process can take varies greatly from case to case due to the very unique facts of each case. Many factors are not within our hands and are often based on government timelines which will fluctuate. We ensure that all deadlines are met on our part to ensure as speedy a process on your behalf as possible.

“I was first introduced to Nita in 2003 after a recommendation directly from the US embassy. After successfully processing an extremely challenging H1B case for two ambitious creative entrepreneurs, NNU Immigration has continued to service our company throughout our growth with a 100% record of success, including H1Bs, O and E2 visas. The results speak for themselves, but it is also worthy of note that all cases are handled with warmth, personality, and a human touch.”

Jonathan, Media & Communications Company

“NNU Immigration service was excellent. NNU Immigration lawyers spent all the time I felt I needed to explain things and advise and I felt reassured and very prepared for my renunciation meeting at the Consulate. I was responded to quickly and efficiently at all times.”

Ana, Private Client

“Nita and her team at NNU Immigration helped us to register our office in the US and to secure E-2 visas for key staff members. Their obvious in-depth knowledge of the various processes, their quick response to our numerous queries and their practical help in compiling our applications were impressive and reassuring. I would highly recommend them for their expertise and their friendly, unflappable approachability”
