F1 Visa renewal

[srinuach]

Hi,
Sorry if a similar question has been posted before.

I am a PhD student in Chemistry from India in usa. my visa expired in july 2006 and i need to visit india sometime in september 2007.

1. I was here in usa for masters in chemical engineering, i did one semester of master's in chemical engineering at alabama, then moved to do master's in chemistry at university of missouri rolla, finished and pursuing my fourth year of phd in chemistry at another university. will i have a problem during visa renewal.

2. Can I renew my visa in Canada or do i need to go back to my country?

3. I am working in total synthesis of natural products (organic synthesis). is this one of those research fields under security clearance research areas?.

4. I have full funding from my university. Should I obtain any financial documents back from my country for the visa or is it okay if i obtain the document from my university stating the proof of funding for my entire PhD study?

Any suggestions would be more than welcome. kindly advice on the above questions.


Honestly, the only reason i am planning to renew my visa in canada is because i cannot find visa appointment during that time in india.

thank you in advance.
with kind regards

Hi,
I have a few questions about the change of visa status.
I plan to change my visa status from H4 to F1 . I want to go to Mexico for that.

Which one do you think is a better option ,Going to India or Canada /Mexico?
If any of you have been to Mexico/Canda /India ,Please Let me know about your

experiences .

In case of rejection of my F1 , Can i come back to US on my H4 (H4 is valid

till 2008)?

Also , do we have to submit the I-539 form for change of status?or only

Ds-156,DS-157, DS-158?

Your reply is needed urgently , and will be greatly appreciated.
