I have a green card that expired in Sept 2012. Can I renew it in Hyderabad or New Delhi as I am planning to travel to the U.S. in May?
Green card renewals are the responsibility of the U.S. Customs and Immigration Services (USCIS), a part of the Department of Homeland Security. USCIS does not have an office at the U.S. Consulate General in Hyderabad. You need to contact the USCIS unit at the U.S. Embassy in New Delhi at NDI.Consular@uscis.dhs.

There was a water drip on my passport due to which there is a small ink run on one side of the photo on my U.S. visa. Is my visa valid for travel?
The Department of Homeland Security uses the photo in your visa to confirm your identity at the port of entry. If the water damage to your photo is obstructing recognition, we recommend you apply for a new visa.
If you seek entry into the U.S. and the immigration official determines that the security and identification features of the visa have been compromised, you will be denied entry.
I have been admitted to the University of Colorado, Boulder for Fall 2013 and plan to schedule my F1 visa interview in June. What supporting documents do I need to bring to demonstrate the financial ability to bear the expenses of my studies and do I also need to show the money required for both years of study?
Congratulations on your admission! You must demonstrate to the officer that you can afford to pay for the first year of your education, lodging and other expenses. How you demonstrate that is completely dependent on how you plan to fund your schooling. Be prepared to show financial evidence that you and/or whoever is supporting you, have sufficient funds to cover your tuition and living expenses during the period of your intended study (e.g., pay slips, income tax documents, original bank books and/or statements, business registration or licenses). In addition to showing sufficient readily available resources for the full first year, you must show how the additional year(s) will be supported. Again, how you show that is by documenting your actual plans. 
I changed my job in Feb. 2011 and during my H1 transfer I forgot to transfer my daughter’s H4 which expired in January 2012. I plan to travel to India for getting my daughter’s visa stamped. Will there be any problem in getting her H4 visa stamped?
As long as the principal applicant can demonstrate that he or she was in status for that entire period of time, eligible H4 members may also be considered to be in status.
Be prepared to provide an explanation and any necessary documentation to show that the H1B visa holder was in status. Please note, to apply for a visa in India, your daughter needs to also be in India. Getting a new visa does not extend your daughter’s status in the U.S.; that is determined at the port of entry when the visa is presented.
My H1B petition was sent back to USCIS in December 2011 and it was reaffirmed by USCIS in February 2013 and received by my employer. Can I submit my passport directly for the visa stamping or do I need to apply for a new visa interview with a new DS-160?
You do not have to apply for a new visa. Please contact the U.S. Consulate at HYDCEA@state.gov for an interview appointment based on the original DS-160.
