I am planning to go home (outside US) for a month vacation this coming Dec. I have a visa stamp from my PREVIOUS employer that will expire on March 15, 2012.
1. Do I still need to go to the US embassy in my home country (where I am going for a vacation) since I have a new employer?
2. Could I use the visa stamp from my previous employer and present it to my point of entry?
3. Let's say I did not move to another employer, is there a time line when I can still use the visa stamp when I leave&go back to US(like for example, mine is nearing the expiration)?
I am a Canadian with J2 visa. I am an engineer and want to work in US to keep up with my career. I am going to apply for EAD. If I don't get, can I switch from J2 to TN. Can my kids still stay on J2?
You can switch back to TN from J-2. What you do has no effect on the children. They derive their status directly from your J-1 spouse.
I have an L-1 Blanket petition and I traveled to US for one week and used that VISA. Part of my job, I need to work in one of our offices outside USA for a year, but will just have to go to US for one week every 2 months. Will that affect my visa since I would not be fulltime working in US? I have M entries in my L-1.
As long as you work full time and on the job described in your L-1B while you are INSIDE USA, it does not matter how long you stay outside USA.
