USA visa

You should seek legal advice from the United States government through a consulate or embassy in your country of residence.

Your country?

"My question is how can I find out whether I would be granted a visa after disclosure of my convictions so that I can apply nearer the time. "

No one here can give an answer that you can rely on, since the only people that issue visas are the US government.

Which country are you a national of?

If your country is under the visa waiver program, you can travel to the US without visa.

If not, request a visa from your closest US Consulate.

I think they might let in in spite of your prior convictions. As long as you are not a Communist too. That would be totally unacceptable to the US Government.

I looked at this official website. One thing I noted is that US visas (B-2 which is what you'd need) are generally for lengthy periods. For an Israeli passport, it's a 10-year multi-entry visa. For a Palestinian passport it's 3 years, multiple entries. I don't see any reason not to apply right now.

I think that speckit has wandered in here and wandered back out. We may never have answers from her so we are really just guessing.

Thanks all for your replies, I live in the uk and have taken note of your replies. Thanks again

If you are a UK national you should be able to travel without a visa under the Visa Waiver Program (VWP). There are some rules and exceptions (for example if you traveled to certain high risk countries after 2011 or if you intend to enroll in a study course), therefore you should read below:

Although visa application fees keep rising, I would hope that starting the application process would cost less than hiring an attorney.
