I'm glad that I found this forum and thank everyone who contributes to it. I'm in the process of beginning my immigration application and therefore have questions....will appreciate answers from any of the people who have knowledge on the subject matters:
1. I have BS, MS (2015 graduate) and 4.5 years of work experience in US, do I still need to take IELTS?
Yes. Everyone has to take IELTS, even native English speakers.
2. I'm applying for myself as primary applicant and also for my wife. I have submitted WES application to get my credentials verified and intend to take IELTS exam next month. My questions is that do I need to get my wife's education verified and have her take IELTS exam as well even though I'm the primary applicant.
You can get points for your wife's education and IELTS, but it isn't necessary if you don't require the extra points.
3. Do her credentials (education, IELTS etc.) help my application or do they have no impact on it?
You can gain up to 10 points for your spouse's education, and up to 20 points for their IELTS.
