Thanks Leon so much for your help I appreciate it so much and I know you are one of the expert here .. about the 67 points I already have it , education 18 years with 4 years work experience have TOEFL IBT with high marks and I could take IELTS and pass it easy ..the problem is my Job not in the 38 job list so as you said I have 2 ways
1. study as international student for one year ,, and I have Q here ..if I take any cheap courses here even it is English in private school or anything else don't need a lot of money is the CIC will care about that if I applied after one year for FSW ..I mean they will ask what you are studied during the year or it doesn't matter for them?

You can call CIC and ask them to clarify but as long as you are on a student visa and studying something, I don't think it matters at all what you study. The main thing is that you have been working or studying for a year.
2. to get Job offer here which I don't know if it will be easy here or not even I graduated with bachelor from my country and Diploma from USA? and you said (( I would say you should work on the job offer (AEO). Explain to potential AEO givers that they are not obligated to hire you when you get your immigration if their situation has changed by that time. Maybe you will find someone)) I couldn't understand this part could you please reexplain it ??
You are asking the employer to apply for an AEO for you. Why should the employer do that? The employer may say, well, I would be open to hiring you but by the time you get your immigration in several months, maybe my situation will have changed and I may not be able to give you a job any more. That is when you can explain to him that he is not taking on any obligations towards you by giving you an AEO.
the third option you mentioned that to get LMO and then change the student visa to work visa and have other ways to immigrate in Canadian experience class for example is I was understanding that correctly

and what do you think about this option ,,there are any conditions to change the student visa to work visa inside Canada?
Of course you can always request to change your visa. To get a work permit, first you need to find an employer. The employer has to apply for an LMO for you. To get that, he needs to prove that he advertised the job and could not find a qualified Canadian. If he gets the LMO, then you can use it to apply for a work permit.
As for LMO vs. AEO, the LMO is harder to get but it allows you to start working sooner. An AEO only allows you to apply for your immigration.
