Yes Scotland hopes to win over the country's 160,000 European nationals with the message that staying in the UK poses a threat to Scotland's EU membership.
David Cameron has promised an in-out referendum on Europe if he remains Prime Minister after 2015.
The pro-independence groups Polish For Yes, Italians For Yes, French For Yes and EU Citizens For An Independent Scotland argue that could put their Scottish residency at risk.
Addressing a meeting of Polish For Yes, Deputy First Minister Nicola Sturgeon urged migrants to make their voices heard in next month's independence referendum.
She said: "With the Westminster parties dancing to Ukip's anti-European tune, Scotland faces the very real prospect of being ripped out of the EU against our will in the event of a No vote.
"With independence we will finally be able to take our place around the European top table, building on our positive relationships with our European partners and ensuring we get the best possible deal for Scotland."
Tomek Borkowy, a Polish actor now living in Scotland, said: "Westminster is treating Polish nationals as freeloaders and scroungers who are coming to the UK to receive benefits. But Poles are hard-working and valued employees.
"The Scottish Government, on the other hand, values the contribution we make to Scottish society. The difference between the two is night and day.
"A No vote is a real threat to our future in Europe."
A Better Together spokesman said: "The facts are clear - if Scotland votes to leave the UK, we would have to reapply to join the EU.
"This would be a very long and complex process, putting at risk the special EU deals we enjoy today as part of the UK.
"We know we would lose our UK rebate, worth £135 for each family in Scotland, and the VAT exemption on kids' clothes. Our opt-outs on the euro and the no- borders immigration scheme would also be at risk. That's a risk we simply don't have to take.
"Alex Salmond is the man who told us he had legal advice on the EU and a separate Scotland. It turns out that wasn't true and he spent thousands of pounds of public money trying to cover that up. Nobody trusts a word he has to say on this issue.
"We should say No Thanks to independence on 18 September."
