The reason why I want to delay my medicals is because i am just about to file for I-485. Maybe in next 30 days at Nebraska Center (which is taking 13 months to process I-485). Also my interview is within the next 2 months.
***do the medicals one week before going for Interview, they will ask have you done medicals reply -YES
Since you told me that we get 1 year from date of medicals on the landing papers I am hoping that by delaying the medicals to about 2 months after the interview (which is in Nov) it gives me a window of 14 months to get my approval notice for I-485. So I dont mind at all if my landing date deadline gets delayed.
So in that case I dont have to take risk and leave the US on I-485.
*** There is no Risk going out of Canada if you have filed I-485, you should have AP to enter and if you still have H1B and I-94 Valid and you do not use EAD then you can enter on H1b visa.
Once I get my US Green Card then I dont need the Canadian GreenCard as I have a decent job here and am well settled here.
** It is up to you.
But I am confused about the following things:
1) Is that certain that we have a deadline for 1 year after date of medicals to land in Canada. (where can I read more about this rule).
YES it is a LAW that Landing permit will be issued for one year from the date of your Medicals and if your Passport is not Valid for one year then LP will be issued till the Expiry date on your Passport, for the law read Immigration law and you may find Instruction on your Forms you filled and you will be told about this when you go for Interview, The Landing date can not be extended it is also law, for more info read on Canada immigration lawyers web site
2)While coming back If the INS officials see the Canadian Permanent Residence stamped on my passport then could they stop me while re entering even on Advance Parole.
***INS has nothing to do with your Canada Immigration they want your immigration status or Visa or Ap for entry to US. Many have landed and came back you are not the only case who is doing to do this first time.
Because I believe we can just keep 1 permanent residency which is either US or Canadian. I am a citizen of India. I am planning to drive to Canada.
** First get the landing paper then think you wand to go by air or by Driving...
3) I dont have any H1-b visa sticker stamped at all on my passport. I just have the approval notice for H1-b which is valid for Dec 2004
(since I had a change of status from J1 to H1 and never left after that). Could not having a stamp complicate things further while re entering on Advance Parole ?
You will not be able to get H1B i in US if you changed from J to H1b, you will or have to use AP, if in the mean time you Visit India try to get H1B Stamp if you are not using EAD if using EAD then H1B visa is not needed only AP will work but better to keep the I-485 filing reciept with you.
why are you worried for Canada info now, better post when you get LP for Canada, still you have to clear your Interview, Medicals and Background check.
