Has your immediate relative petitioned you to come to the United States and then passed away suddenly and your I-130 has been denied due to the death of your immediate relative?
The best option for you would be the Humanitarian Reinstatement which makes it possible for you to have the I-130 reinstated so you don't have to start the immigration process all over again. Assuming you and the Substitute Sponsor will experience hardship if your I-130 is not reinstated, and the hardship is documented, the Humanitarian Reinstatement will have the best chance for approval.
It includes all relevant cover letters, forms, exhibits, and supporting evidence. It has been prepared by an expert Immigration attorney. Thus this book will allow you to see a guide of how it's done, prepared and submitted.
