You need to schedule a consultation with an immigration attorney and provide him or her a copy of your case records. Your question requires a detailed review of your case and cannot be answered on a pubic forum such as Avvo. Bonne chance!
To receive an E visa, your business has to have the nationality of a treaty country (not the United States). E visa cases are complex and E visa cases based on the purchase of a franchise can be tricky. You should consult an immigration attorney to review your business plans and determine if you are eligible for the visa. You may also need to retain a business or franchise attorney to structure a deal with the franchisor that would allow you to buy the business despite your nationality.
You will need to provide an Affidavit of Support with evidence you meet the income requirements when filing for your wife. Please see the links below for information.
You should consult an immigration attorney to determine whether your wife is eligible to adjust her status in the United States before filing any petitions on her behalf. If she is not legally present, she may be unable to adjust status without leaving the country under current regulations.
It does not mean you are necessarily going to be denied. We can't tell you that because none of us were there and haven't seen your evidence. Keep checking your case status at www.uscis.gov. If you are denied, schedule a consultation with an immigration attorney immediately.
If your father was convicted, ICE can place him in removal, no matter if he was only sentenced to probation. Your family needs to hire an immigration attorney to determine what can be done to keep him here.
I agree with Mr. Capriotti. It is always best to stay in status during the adjustment process. Things happen - sponsors lose jobs and are unable to provide the required support, co-sponsors back out, applications are rejected by USCIS mistake, etc. Don't risk it.
Nothing in your question gives us any information about potential problems that might arise in your case at the U.S. Embassy in India. If your current attorney is not an immigration attorney, retain an immigration attorney well before the appointment date. There are plenty of excellent immigration attorneys on Avvo to choose from or you can find one at the link below.
