How long have you been in business?

2022 is NNU Immigration Limited’s 10th year in business. The firm 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.

Please read more about our Team.

 

Do I need to come into your office and meet you in person to retain you, or to receive legal services?


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.

 

What are your business hours?

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.

 

Do you charge for consultations?

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.

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.”
